ð19Þ FOREWORD*
In 1911, The American Society of Mechanical Engineers established the Boiler and Pressure Vessel Committee to for-
mulate standard rules for the construction of steam boilers and other pressure vessels. In 2009, the Boiler and Pressure
Vessel Committee was superseded by the following committees:
(a) Committee on Power Boilers (I)
(b) Committee on Materials (II)
(c) Committee on Construction of Nuclear Facility Components (III)
(d) Committee on Heating Boilers (IV)
(e) Committee on Nondestructive Examination (V)
(f) Committee on Pressure Vessels (VIII)
(g) Committee on Welding, Brazing, and Fusing (IX)
(h) Committee on Fiber-Reinforced Plastic Pressure Vessels (X)
(i) Committee on Nuclear Inservice Inspection (XI)
(j) Committee on Transport Tanks (XII)
(k) Technical Oversight Management Committee (TOMC)
Where reference is made to “the Committee” in this Foreword, each of these committees is included individually and
collectively.
The Committee’s function is to establish rules of safety relating only to pressure integrity, which govern the
construction** of boilers, pressure vessels, transport tanks, and nuclear components, and the inservice inspection of nu-
clear components and transport tanks. The Committee also interprets these rules when questions arise regarding their
intent. The technical consistency of the Sections of the Code and coordination of standards development activities of the
Committees is supported and guided by the Technical Oversight Management Committee. This Code does not address
other safety issues relating to the construction of boilers, pressure vessels, transport tanks, or nuclear components, or
the inservice inspection of nuclear components or transport tanks. Users of the Code should refer to the pertinent codes,
standards, laws, regulations, or other relevant documents for safety issues other than those relating to pressure integ-
rity. Except for Sections XI and XII, and with a few other exceptions, the rules do not, of practical necessity, reflect the
likelihood and consequences of deterioration in service related to specific service fluids or external operating environ-
ments. In formulating the rules, the Committee considers the needs of users, manufacturers, and inspectors of pressure
vessels. The objective of the rules is to afford reasonably certain protection of life and property, and to provide a margin
for deterioration in service to give a reasonably long, safe period of usefulness. Advancements in design and materials
and evidence of experience have been recognized.
This Code contains mandatory requirements, specific prohibitions, and nonmandatory guidance for construction ac-
tivities and inservice inspection and testing activities. The Code does not address all aspects of these activities and those
aspects that are not specifically addressed should not be considered prohibited. The Code is not a handbook and cannot
replace education, experience, and the use of engineering judgment. The phrase engineering judgment refers to technical
judgments made by knowledgeable engineers experienced in the application of the Code. Engineering judgments must
be consistent with Code philosophy, and such judgments must never be used to overrule mandatory requirements or
specific prohibitions of the Code.
The Committee recognizes that tools and techniques used for design and analysis change as technology progresses
and expects engineers to use good judgment in the application of these tools. The designer is responsible for complying
with Code rules and demonstrating compliance with Code equations when such equations are mandatory. The Code
neither requires nor prohibits the use of computers for the design or analysis of components constructed to the
* The information contained in this Foreword is not part of this American National Standard (ANS) and has not been processed in accordance
with ANSI's requirements for an ANS. Therefore, this Foreword may contain material that has not been subjected to public review or a con-
sensus process. In addition, it does not contain requirements necessary for conformance to the Code.
** Construction, as used in this Foreword, is an all-inclusive term comprising materials, design, fabrication, examination, inspection, testing,
certification, and pressure relief.

requirements of the Code. However, designers and engineers using computer programs for design or analysis are cau-
tioned that they are responsible for all technical assumptions inherent in the programs they use and the application of
these programs to their design.
The rules established by the Committee are not to be interpreted as approving, recommending, or endorsing any pro-
prietary or specific design, or as limiting in any way the manufacturer’s freedom to choose any method of design or any
form of construction that conforms to the Code rules.
The Committee meets regularly to consider revisions of the rules, new rules as dictated by technological development,
Code Cases, and requests for interpretations. Only the Committee has the authority to provide official interpretations of
this Code. Requests for revisions, new rules, Code Cases, or interpretations shall be addressed to the Secretary in writing
and shall give full particulars in order to receive consideration and action (see Submittal of Technical Inquiriesto the
Boiler and Pressure Vessel Standards Committees). Proposed revisions to the Code resulting from inquiries will be pre-
sented to the Committee for appropriate action. The action of the Committee becomes effective only after confirmation
by ballot of the Committee and approval by ASME. Proposed revisions to the Code approved by the Committee are sub-
mitted to the American National Standards Institute (ANSI) and published at http://go.asme.org/BPVCPublicReview to
invite comments from all interested persons. After public review and final approval by ASME, revisions are published at
regular intervals in Editions of the Code.
The Committee does not rule on whether a component shall or shall not be constructed to the provisions of the Code.
The scope of each Section has been established to identify the components and parameters considered by the Committee
in formulating the Code rules.
Questions or issues regarding compliance of a specific component with the Code rules are to be directed to the ASME
Certificate Holder (Manufacturer). Inquiries concerning the interpretation of the Code are to be directed to the Commit-
tee. ASME is to be notified should questions arise concerning improper use of the ASME Single Certification Mark.
When required by context in this Section, the singular shall be interpreted as the plural, and vice versa, and the fem-
inine, masculine, or neuter gender shall be treated as such other gender as appropriate.

STATEMENT OF POLICY ON THE USE OF THE ASME SINGLE
CERTIFICATION MARK AND CODE AUTHORIZATION IN
ADVERTISING
ASME has established procedures to authorize qualified organizations to perform various activities in accordance
with the requirements of the ASME Boiler and Pressure Vessel Code. It is the aim of the Society to provide recognition
of organizations so authorized. An organization holding authorization to perform various activities in accordance with
the requirements of the Code may state this capability in its advertising literature.
Organizations that are authorized to use the ASME Single Certification Mark for marking items or constructions that
have been constructed and inspected in compliance with the ASME Boiler and Pressure Vessel Code are issued Certifi-
cates of Authorization. It is the aim of the Society to maintain the standing of the ASME Single Certification Mark for the
benefit of the users, the enforcement jurisdictions, and the holders of the ASME Single Certification Mark who comply
with all requirements.
Based on these objectives, the following policy has been established on the usage in advertising of facsimiles of the
ASME Single Certification Mark, Certificates of Authorization, and reference to Code construction. The American Society
of Mechanical Engineers does not “approve,” “certify,” “rate,” or “endorse” any item, construction, or activity and there
shall be no statements or implications that might so indicate. An organization holding the ASME Single Certification Mark
and/or a Certificate of Authorization may state in advertising literature that items, constructions, or activities “are built
(produced or performed) or activities conducted in accordance with the requirements of the ASME Boiler and Pressure
Vessel Code,” or “meet the requirements of the ASME Boiler and Pressure Vessel Code.”An ASME corporate logo shall not
be used by any organization other than ASME.
The ASME Single Certification Mark shall be used only for stamping and nameplates as specifically provided in the
Code. However, facsimiles may be used for the purpose of fostering the use of such construction. Such usage may be
by an association or a society, or by a holder of the ASME Single Certification Mark who may also use the facsimile
in advertising to show that clearly specified items will carry the ASME Single Certification Mark.
STATEMENT OF POLICY ON THE USE OF ASME MARKING TO
IDENTIFY MANUFACTURED ITEMS
The ASME Boiler and Pressure Vessel Code provides rules for the construction of boilers, pressure vessels, and nuclear
components. This includes requirements for materials, design, fabrication, examination, inspection, and stamping. Items
constructed in accordance with all of the applicable rules of the Code are identified with the ASME Single Certification
Mark described in the governing Section of the Code.
Markings such as “ASME,” “ASME Standard,” or any other marking including “ASME” or the ASME Single Certification
Mark shall not be used on any item that is not constructed in accordance with all of the applicable requirements of the
Code.
Items shall not be described on ASME Data Report Forms nor on similar forms referring to ASME that tend to imply
that all Code requirements have been met when, in fact, they have not been. Data Report Forms covering items not fully
complying with ASME requirements should not refer to ASME or they should clearly identify all exceptions to the ASME
requirements.

ð19ÞSUBMITTAL OF TECHNICAL INQUIRIES TO THE BOILER AND
PRESSURE VESSEL STANDARDS COMMITTEES
1 INTRODUCTION
(a) The following information provides guidance to Code users for submitting technical inquiries to the applicable
Boiler and Pressure Vessel (BPV) Standards Committee (hereinafter referred to as the Committee). See the guidelines
on approval of new materials under the ASME Boiler and Pressure Vessel Code in Section II, Part D for requirements for
requests that involve adding new materials to the Code. See the guidelines on approval of new welding and brazing ma-
terials in Section II, Part C for requirements for requests that involve adding new welding and brazing materials (“con-
sumables”) to the Code.
Technical inquiries can include requests for revisions or additions to the Code requirements, requests for Code Cases,
or requests for Code Interpretations, as described below:
(1) Code Revisions. Code revisions are considered to accommodate technological developments, to address admin-
istrative requirements, to incorporate Code Cases, or to clarify Code intent.
(2) Code Cases. Code Cases represent alternatives or additions to existing Code requirements. Code Cases are writ-
ten as a Question and Reply, and are usually intended to be incorporated into the Code at a later date. When used, Code
Cases prescribe mandatory requirements in the same sense as the text of the Code. However, users are cautioned that
not all regulators, jurisdictions, or Owners automatically accept Code Cases. The most common applications for Code
Cases are as follows:
(-a) to permit early implementation of an approved Code revision based on an urgent need
(-b) to permit use of a new material for Code construction
(-c) to gain experience with new materials or alternative requirements prior to incorporation directly into the
Code
(3) Code Interpretations
(-a) Code Interpretations provide clarification of the meaning of existing requirements in the Code and are pre-
sented in Inquiry and Reply format. Interpretations do not introduce new requirements.
(-b) If existing Code text does not fully convey the meaning that was intended, or conveys conflicting require-
ments, and revision of the requirements is required tosupport the Interpretation, an Intent Interpretation will be issued
in parallel with a revision to the Code.
(b) Code requirements, Code Cases, and Code Interpretations established by the Committee are not to be considered
as approving, recommending, certifying, or endorsing any proprietary or specific design, or as limiting in any way the
freedom of manufacturers, constructors, or Owners to choose any method of design or any form of construction that
conforms to the Code requirements.
(c) Inquiries that do not comply with the following guidance or that do not provide sufficient information for the Com-
mittee’s full understanding may result in the request being returned to the Inquirer with no action.
2 INQUIRY FORMAT
Submittals to the Committee should include the following information:
(a) Purpose. Specify one of the following:
(1) request for revision of present Code requirements
(2) request for new or additional Code requirements
(3) request for Code Case
(4) request for Code Interpretation
(b) Background. The Inquirer should provide the information needed for the Committee’s understanding of the In-
quiry, being sure to include reference to the applicable Code Section, Division, Edition, Addenda (if applicable), para-
graphs, figures, and tables. Preferably, the Inquirer should provide a copy of, or relevant extracts from, the specific
referenced portions of the Code.

(c) Presentations. The Inquirer may desire to attend or be asked to attend a meeting of the Committee to make a for-
mal presentation or to answer questions from the Committee members with regard to the Inquiry. Attendance at a BPV
Standards Committee meeting shall be at the expense of the Inquirer. The Inquirer’s attendance or lack of attendance at
a meeting will not be used by the Committee as a basis for acceptance or rejection of the Inquiry by the Committee. How-
ever, if the Inquirer’s request is unclear, attendance by the Inquirer or a representative may be necessary for the Com-
mittee to understand the request sufficiently to be able to provide an Interpretation. If the Inquirer desires to make a
presentation at a Committee meeting, the Inquirer should provide advance notice to the Committee Secretary, to ensure
time will be allotted for the presentation in the meeting agenda. The Inquirer should consider the need for additional
audiovisual equipment that might not otherwise be provided by the Committee. With sufficient advance notice to the
Committee Secretary, such equipment may be made available.
3 CODE REVISIONS OR ADDITIONS
Requests for Code revisions or additions should include the following information:
(a) Requested Revisions or Additions. For requested revisions, the Inquirer should identify those requirements of the
Code that they believe should be revised, and should submit a copy of, or relevant extracts from, the appropriate require-
ments as they appear in the Code, marked up with the requested revision. For requested additions to the Code, the In-
quirer should provide the recommended wording and should clearly indicate where they believe the additions should be
located in the Code requirements.
(b) Statement of Need. The Inquirer should provide a brief explanation of the need for the revision or addition.
(c) Background Information. The Inquirer should provide background information to support the revision or addition,
including any data or changes in technology that form the basis for the request, that will allow the Committee to ade-
quately evaluate the requested revision or addition. Sketches, tables, figures, and graphs should be submitted, as appro-
priate. The Inquirer should identify any pertinent portions of the Code that would be affected by the revision or addition
and any portions of the Code that reference the requested revised or added paragraphs.
4 CODE CASES
Requests for Code Cases should be accompanied by a statement of need and background information similar to that
described in 3(b) and 3(c), respectively, for Code revisions or additions. The urgency of the Code Case (e.g., project un-
derway or imminent, new procedure) should be described. In addition, it is important that the request is in connection
with equipment that will bear the ASME Single Certification Mark, with the exception of Section XI applications. The pro-
posed Code Case should identify the Code Section and Division, and should be written as a Question and a Reply, in the
same format as existing Code Cases. Requests for Code Cases should also indicate the applicable Code Editions and Ad-
denda (if applicable) to which the requested Code Case applies.
5 CODE INTERPRETATIONS
(a) Requests for Code Interpretations should be accompanied by the following information:
(1) Inquiry. The Inquirer should propose a condensed and precise Inquiry, omitting superfluous background infor-
mation and, when possible, composing the Inquiry in such a way that a “yes” or a “no” Reply, with brief limitations or
conditions, if needed, can be provided by the Committee. The proposed question should be technically and editorially
correct.
(2) Reply. The Inquirer should propose a Reply that clearly and concisely answers the proposed Inquiry question.
Preferably, the Reply should be “yes” or “no,” with brief limitations or conditions, if needed.
(3) Background Information. The Inquirer should provide any need or background information, such as described in
3(b) and 3(c), respectively, for Code revisions or additions, that will assist the Committee in understanding the proposed
Inquiry and Reply.
If the Inquirer believes a revision of the Code requirements would be helpful to support the Interpretation, the In-
quirer may propose such a revision for consideration by the Committee. In most cases, such a proposal is not necessary.
(b) Requests for Code Interpretations should be limited to an Interpretation of a particular requirement in the Code or
in a Code Case. Except with regard to interpreting a specific Code requirement, the Committee is not permitted to con-
sider consulting-type requests such as the following:
(1) a review of calculations, design drawings, welding qualifications, or descriptions of equipment or parts to de-
termine compliance with Code requirements

6 SUBMITTALS
(a) Submittal. Requests for Code Interpretation should preferably be submitted through the online Interpretation Sub-
mittal Form. The form is accessible at http://go.asme.org/InterpretationRequest. Upon submittal of the form, the In-
quirer will receive an automatic e-mail confirming receipt. If the Inquirer is unable to use the online form, the
Inquirer may mail the request to the following address:
Secretary
ASME Boiler and Pressure Vessel Committee
Two Park Avenue
New York, NY 10016-5990
All otherInquiries should be mailed to the Secretary of the BPV Committee at the address above. Inquiries are unlikely
to receive a response if they are not written in clear, legible English. They must also include the name of the Inquirer and
the company they represent or are employed by, if applicable, and the Inquirer’s address, telephone number, fax num-
ber, and e-mail address, if available.
(b) Response. The Secretary of the appropriate Committee will provide a written response, via letter or e-mail, as ap-
propriate, to the Inquirer, upon completion of the requested action by the Committee. Inquirers may track the status of
their Interpretation Request at http://go.asme.org/Interpretations.

CROSS-REFERENCING AND STYLISTIC CHANGES IN THE BOILER
AND PRESSURE VESSEL CODE
There have been structural and stylistic changes to BPVC, starting with the 2011 Addenda, that should be noted to aid
navigating the contents. The following is an overview of the changes:
Subparagraph Breakdowns/Nested Lists Hierarchy
• First-level breakdowns are designated as (a), (b), (c), etc., as in the past.
• Second-level breakdowns are designated as (1), (2), (3), etc., as in the past.
• Third-level breakdowns are now designated as (-a), (-b), (-c), etc.
• Fourth-level breakdowns are now designated as (-1), (-2), (-3), etc.
• Fifth-level breakdowns are now designated as (+a), (+b), (+c), etc.
• Sixth-level breakdowns are now designated as (+1), (+2), etc.
Footnotes
With the exception of those included in the front matter (roman-numbered pages), all footnotes are treated as end-
notes. The endnotes are referenced in numeric order and appear at the end of each BPVC section/subsection.
Submittal of Technical Inquiries to the Boiler and Pressure Vessel Standards Committees
Submittal of Technical Inquiries to the Boiler and Pressure Vessel Standards Committees has been moved to the front
matter. This information now appears in all Boiler Code Sections (except for Code Case books).
Cross-References
It is our intention to establish cross-reference link functionality in the current edition and moving forward. To facil-
itate this, cross-reference style has changed. Cross-references within a subsection or subarticle will not include the des-
ignator/identifier of that subsection/subarticle. Examples follow:
• (Sub-)Paragraph Cross-References. The cross-references to subparagraph breakdowns will follow the hierarchy of
the designators under which the breakdown appears.
– If subparagraph (-a) appears in X.1(c)(1) and is referenced in X.1(c)(1), it will be referenced as (-a).
– If subparagraph (-a) appears in X.1(c)(1) but is referenced in X.1(c)(2), it will be referenced as (1)(-a).
– If subparagraph (-a) appears in X.1(c)(1) but is referenced in X.1(e)(1), it will be referenced as (c)(1)(-a).
– If subparagraph (-a) appears in X.1(c)(1) but is referenced in X.2(c)(2), it will be referenced as X.1(c)(1)(-a).
• Equation Cross-References. The cross-references to equations will follow the same logic. For example, if eq. (1) ap-
pears in X.1(a)(1) but is referenced in X.1(b), it will be referenced as eq. (a)(1)(1). If eq. (1) appears in X.1(a)(1) but
is referenced in a different subsection/subarticle/paragraph, it will be referenced as eq. X.1(a)(1)(1).

SCOPE AND JURISDICTION
KG-100 SCOPE
KG-101 INTENT
The rules of this Division constitute requirements for
the design, construction, inspection, and overpressure
protection of metallic pressure vessels with design pres-
sures generally above 10 ksi (70 MPa). However, it is
not the intent of this Division to establish maximum pres-
sure limits for either Section VIII, Division 1 or 2, nor
minimum pressure limits for this Division. Specific pres-
sure limitations for vessels constructed to the rules of this
Division may be imposed elsewhere in this Division for
various types of fabrication. Whenever Construction ap-
pears in this document, it may be considered an
all-inclusive term comprising materials, design, fabrica-
tion, examination, inspection, testing, certification, and
pressure relief.
KG-102 DESCRIPTION
Pressure vessels within the scope of this Division are

instrumentation, such as gages and instruments, for
which rules are not provided by this Division (see Article
KD-6).
KG-116 OVERPRESSURE PROTECTION
Pressure relief devices shall satisfy the requirements of
Part KR.
KG-117 COMBINATION UNITS
When a pressure vessel unit consists of more than one
independent pressure chamber, only the parts of cham-
bers which are within the scope of this Division need to
be constructed in compliance with its provisions (see
Articles KD-1 and KG-3).
KG-120 CLASSIFICATIONS OUTSIDE THE
SCOPE OF THIS DIVISION
The following classes of pressure-containing equip-
ment are not within the scope of this Division:
(a) those within the scopes of other Sections of this
Code
(b) fired process tubular heaters
(c) pressure-containing equipment that is an integral
part or component of a rotating or reciprocating mechan-
ical device, such as
(1) pumps
(2) compressors
(3) turbines
(4) generators
(5) engines
(6) hydraulic or pneumatic cylinders
where the primary design considerations and/or stresses
are derived from the functional requirements of the
device
(d) structures whose primary function is the transport
of fluids from one location to another within a system of
which they are integral parts (piping systems)
KG-121 STAMPING OF VESSELS OUTSIDE THE
SCOPE OF THIS DIVISION
Any pressure vessel which meets all applicable require-
ments of this Division may be stamped with the Certifica-
tion Mark with U3 Designator.
The Certification Mark is an ASME symbol identifying a
product as meeting Code requirements. The Designator is
a symbol used in conjunction with the Certification Mark
for the scope of activity described in a Manufacturer's
Certificate of Authorization.
KG-130 ASSEMBLY AND TESTING OF
VESSELS AT FIELD OR
INTERMEDIATE SITES
A field site is a location of final permanent installation
of the pressure equipment. An intermediate site is a tem-
porary location under the control of the Certificate
Holder. The location of an intermediate site is other than
that listed on the Certificate of Authorization and other
than a field site. All Code activities may be performed at
intermediate or field sites by the Certificate Holder pro-
vided they comply with all Code requirements, and con-
trol of those activities is described in the Certificate
Holder's Quality Control System. Assembly and testing
of vessels constructed to this Division at intermediate
or field sites shall be performed using one of the following
three alternatives:
(a) The Manufacturer of the vessel completes the vessel
in the field or at an intermediate site.
(b) The Manufacturer of parts of a vessel to be com-
pleted in the field or at an intermediate site by some other
party stamps these parts in accordance with Code rules
and supplies the Manufacturer’s Data Report Form K-2
to the other party. The other party, who shall also hold
a valid U3 Certificate of Authorization, makes the final as-
sembly, required nondestructive examination (NDE), and
final pressure test; completes the Manufacturer’s Data Re-
port Form K-1; and stamps the vessel. The Certificate of
Authorization is a document issued by the Society that
authorizes the use of the ASME Certification Mark and ap-
propriate Designator for a specified time and for a speci-
fied scope of activity.
(c) Code work at field or intermediate sites is com-
pleted by a Certificate Holder of a valid U3 Certificate of
Authorization other than the Manufacturer. The Certifi-
cate Holder performing the work is required to supply a
Manufacturer’s Data Report Form K-2 covering the por-
tion of the work completed by his organization (including
data on the pressure test if conducted by the Certificate
Holder performing the fieldwork) to the Manufacturer re-
sponsible for the Code vessel. The Manufacturer applies
his Certification Mark with U3 Designator in the presence
of a representative from his Inspection Agency and com-
pletes the Manufacturer’s Data Report Form K-1 with his
Inspector.

standards for pressure vessel parts. Specific editions of
standards referenced in this Division are shown in Table
KG-141.
KG-142 STANDARD PARTS
Standard pressure parts which comply with an ASME
product standard shall be made of materials permitted
by this Division (see Part KM).
KG-150 UNITS OF MEASUREMENT
(a) Either U.S. Customary, SI, or any local customary
units may be used to demonstrate compliance with re-
quirements of this edition related to materials, fabrica-
tion, examination, inspection, testing, certification, and
overpressure protection.
(b) A single system of units shall be used for all aspects
of design except where otherwise permitted by this Divi-
sion. When components are manufactured at different lo-
cations where local customary units are different than
those used for the general design, the local units may be
used for the design and documentationof that compo-
nent, within the limitations given in (c). Similarly, for pro-
prietary components or those uniquely associated with a
system of units different than that used for the general
design, the alternate units may be used for the design
and documentation of that component, within the limita-
tions given in (c).
(c) For any single equation, all variables shall be ex-
pressed in a single system of units. Calculations using
any material data published in this Division or Section
II, Part D (e.g., allowable stresses, physical properties, ex-
ternal pressure design factor B, etc.) shall be carried out
in one of the standard units given in Table KG-150. When
separate equations are provided for U.S. Customary and
SI units, those equations must be executed using variables
in the units associated with the specific equation. Data ex-
pressed in other units shall be converted to U.S. Custom-
ary or SI units for use in these equations. The result
obtained from execution of these equations or any other
calculations carried out in either U.S. Customary or SI
units may be converted to other units.
(d) Production, measurement, and test equipment,
drawings, welding procedure specifications, welding pro-
cedure and performance qualifications, and other fabrica-
tion documents may be in U.S. Customary, SI, or local
customary units in accordance with the fabricator’s prac-
tice. When values shown in calculations and analysis, fab-
rication documents, or measurement and test equipment
are in different units, any conversions necessary for ver-
ification of Code compliance and to ensure that dimen-
sional consistency is maintained shall be in accordance
with the following:
(1) Conversion factors shall be accurate to at least
four significant figures.
(2) The results of conversions of units shall be ex-
pressed to a minimum of three significant figures.
(e) Conversion of units, using the precision specified
previously, shall be performed to ensure that dimensional
consistency is maintained. Conversion factors between
U.S. Customary and SI units may be found in the Nonman-
datory Appendix I, Guidance for the Use of U.S. Customary
and SI Units, in the ASME Boiler and Pressure Vessel Code.
Whenever local customary units are used, the Manufac-
turer shall provide the source of the conversion factors
which shall be subject to verification and acceptance by
the Authorized Inspector or Certified Individual.
(f) Dimensions shown in the text, tables, and figures,
whether given as a decimal or a fraction, may be taken
as a decimal or a fraction and do not imply any manufac-
turing precision or tolerance on the dimension.
(g)Material that has been manufactured and certified
to either the U.S. Customary or SI material specification
(e.g., SA-516M) may be used regardless of the unit system
used in design. Standard fittings (e.g., flanges and elbows)
that have been certified to either U.S. Customary or SI
units may be used regardless of the equations or any
other calculations carried out in either U.S. Customary
or SI units system used in design.
(h) All entries on a Manufacturer’s Data Report and
data for Code‐required nameplate marking shall be in
units consistent with the fabrication drawings for the

ARTICLE KG-3
RESPONSIBILITIES AND DUTIES
KG-300 GENERAL
The User, Manufacturer, and Inspector involved in the
production and certification of vessels according to this
Division have definite responsibilities and duties in meet-
ing the requirements of this Division. The responsibilities
and duties set forth in the following relate only to compli-
ance with this Division, and are not to be construed as in-
volving contractual relations or legal liabilities. Whenever
User appears in this document, it may be considered to
apply also to an Agent (e.g., designee or licensor) acting
in his behalf.
KG-310 USER’S RESPONSIBILITY
It is the responsibility of the User or an Agent acting on
behalf of the User to provide a User's Design Specification
for each pressure vessel to be constructed in accordance
with this Division. The User's Design Specification shall
contain sufficient detail to provide a complete basis for
design and construction in accordance with this Division.
It is the User's responsibility to specify, or cause to be
specified, the effective Code Edition to be used for
construction.
A single User's Design Specification may be prepared to
support the design of more than one pressure vessel
when all details of the construction are identical for each
pressure vessel. The location of installation shall be a sin-
gle, specific jurisdiction, provided that all technical re-
quirements of the User's Design Specification are
identical (see Article KG-1).
(a) The designated agent may be
(1) a design agency specifically engaged by the User
(2) the Manufacturer of a system for a specific ser-
vice that includes a pressure vessel as a component that
is purchased by the User, or
(3) an organization that offers pressure vessels for
sale or lease for specific services
(b) The User may select more than one designated
agent to obtain the most experience-based advice in sev-
eral areas of expertise when needed (e.g., design, metal-
lurgy, fabrication, pressure relief).
(c) A designated agent may be self-appointed as such
by accepting certain responsibilities of a designated
agent, as in the case of vessels designed, manufactured
(built) for stock, and intended for operation in a specific
application.
(d) The Design Specification shall contain sufficient de-
tail to provide a complete basis for Division 3 design and
construction. Such requirements shall not result in design
or construction that fails to conform with the rules of this
Division.
KG-311 USER’S DESIGN SPECIFICATION
The User’s Design Specification shall include the
following.
KG-311.1 Vessel Identification.
(a) vessel number
(b) name, function, purpose
(c) service fluid
KG-311.2 Vessel Configuration.
(a) shape
(b) vertical or horizontal
(c) nominal size or volume capacity
(d) support method and location, including the founda-
tion type and allowable loading, if applicable (see KD-110
and Article KD-7)
(e) construction type
(f) functions and boundaries of the items covered in
KG-110
(g) items furnished by Manufacturer
(h) items furnished by User
KG-311.3 Controlling Dimensions.
(a) outline drawings
(b) openings, connections, closures
(1) quantity of each
(2) type and size
(3) purpose
(4) location, elevation, and orientationKG-311.4 Design Criteria.
(a) Design Pressure. Design pressure is the pressure at
the top of the vessel and which, together with the applic-
able coincident (metal) temperature, is stamped on the
nameplate. The pressure at the top of the vessel is also
the basis for the pressure setting of the pressure relief de-
vices protecting the vessel.
(b) Design Temperature. The maximum mean metal
temperature specified by the User, at design pressure.
See KD-112. This is the design temperature that is to be
stamped on the vessel.
(c) More than one combination of design pressure and
temperature may be specified.

(d) Minimum Design Metal Temperature (MDMT). The
MDMT is the lowest temperature to which the vessel will
be exposed when the primary stresses at any location in
the vessel are greater than 6 ksi (40 MPa)(see KM-234).
This temperature shall be determined considering the
lowest process temperature to which the vessel will nor-
mally be exposed in service, including process upsets,
dumps, jet impingement, etc. Also, see KD-112 and
KD-113.
(e) Thermal gradients across the vessel sections.
KG-311.5 Operating Conditions.
(a) operating pressure at coincident fluid temperature.
The operating pressure is the maximum sustained process
pressure that is expected in service. The operating pres-
sure shall not exceed the design pressure. This pressure
is expressed as a positive value, and may be internal or
external to the vessel.
(b) upset and other combinations of operating pres-
sures and coincident fluid temperature in sufficient detail
to constitute an adequate basis for selecting materials
(c) proposed methods of heating and cooling, as well as
those upset conditions that could lead to rapid heating or
cooling of the vessel surfaces
(d) cyclic operating data and conditions
KG-311.6 Contained Fluid Data.
(a) phase (liquid, gaseous, dual)
(b) density
(c) unusual thermodynamic properties

ARTICLE KG-5
ADDITIONAL GENERAL REQUIREMENTS FOR COMPOSITE
REINFORCED PRESSURE VESSELS (CRPV)
KG-500 GENERAL REQUIREMENTS
The following Article provides additional general re-
quirements for the manufacture of Composite Reinforced
Pressure Vessels (CRPV).
KG-510 SCOPE
This construction method uses a laminate of continu-
ous unidirectional filaments of a specified glass or carbon
fiber with a specified resin that is circumferentially
wound in a systematic manner under controlled tension
over a cylindrical metallic layer and cured in place. Open-
ings are not permitted in the laminate. Metallic ends and
nozzles complete the construction; see Section X, Manda-
tory Appendix 10, Figures 10-200.2-1, 10-200.2-2, and
10-200.2-3.
KG-511 METALLIC LAYER
The outside diameter of the metallic layer in the rein-
forced area shall not exceed 60 in. (1.52 m). The thickness
of the metallic layer shall not be less than 0.25 in. (6 mm).
KG-512 SERVICE LIFE
Service life for CRPV constructed under the rules of this
Division shall be limited to twenty years from the date of
manufacture as noted on Form CRPV-1A.
KG-513 APPLICATION SPECIFIC TESTS AND
OTHER REQUIREMENTS
This Division does not include requirements or rules
for tests that may be appropriate for certain applications
(e.g., fire tests, drop tests, projectile impact tests). For
some applications, it may be necessary to consider addi-
tional conditions such as exposure to fire and projectile
impact damage.
KG-514 UPPER LIMIT OF DESIGN PRESSURE
The internal design pressure for CRPV shall not be
greater than 15,000 psi (103 MPa).
KG-515 SERVICE PRESSURE AND WORKING
PRESSURE
In some standards and regulations used in ambient
temperature compressed gas transport service, the term
“service pressure” is used to indicate the pressure in
the vessel at a temperature of 68°F (20°C). In other stan-
dards and regulations, the term “working pressure” is
used with the same definition. In these standards and reg-
ulations it is generally allowable for the service or work-
ing pressure to be exceeded as the gas is heated beyond
68°F (20°C) during filling or due to atmospheric heating.
For pressure vessels to be used in transport service con-
structed to this Code, the service pressure and the work-
ing pressure shall be the maximum expected pressure at a
temperature of 68°F (20°C). The service pressure or the
working pressure or both shall be defined in the User’s
Design Specification. The working pressure, service pres-
sure, or the expected pressure due to heating during fill-
ing or atmospheric heating shall not exceed the design
pressure of the vessel at the design temperature.
KG-516 PROTECTIVE LAYER
Additional requirements regarding specification of a
protective layer for the CRPV in the User's Design Speci-
fication can be found in Section X, Mandatory Appendix
10, 10-200.3.
KG-517 REQUIREMENTS FOR CYCLIC PRESSURE
QUALIFICATION TEST
In addition to the total number of operating cycles dur-
ing the life of the CRPV, the User's Design Specification
shall state if the temperature of the intended service will
be controlled. If the intent is to control the temperature of
service, the number of cycles colder than 30°F (0°C), the
number of cycles between 30°F (0°C) and 110°F (45°C),
and the number of cycles warmer than 110°F (45°C) shall
be noted. If the service will be in ambient conditions with
no intent to control the temperature, there is no require-
ment to report the number of cycles in the aforemen-
tioned temperature ranges.
KG-518 LAMINATE TENSILE STRENGTH AND
ELASTIC MODULUS
The User’s Design Specification shall state the required
minimum tensile strength and the nominal elastic modu-
lus for the laminate in the maximum property direction
(parallel to the fiber direction).

ARTICLE KM-2
MECHANICAL PROPERTY TEST REQUIREMENTS FOR METALS
KM-200 GENERAL REQUIREMENTS
As permitted by KM-100, all forms of metal products
may be usedsubject to meeting the requirements of the
material specification as well as the mechanical test and
examination requirements of this Division.
KM-201 DEFINITION OF THICKNESS
The requirements in this Article make reference to a
thickness. For the purpose intended, the following defini-
tions of thickness T at the time of heat treatment apply.
KM-201.1 Plates. The thickness is the dimension of
the short transverse direction.
KM-201.2 Forgings. The thickness is the dimension
defined as follows:
(a) for hollow forgings in which the axial length is
greater than the radial thickness, the thickness is mea-
sured between the minimum inside and maximum out-
side surfaces (radial thickness), excluding flanges
(protrusions) whose thicknesses are less than the wall
thickness of the cylinder
(b) for disk forgings in which the axial length is less
than or equal to outside diameter, the thickness is the ax-
ial length
(c) for ring forgings where the maximum axial length is
less than the radial thickness, the maximum axial dimen-
sion is considered the thickness
(d) for rectangular solid forgings, the least rectangular
dimension is the thickness
(e) for round, hexagonal, and octagonal solid forgings,
the nominal thickness is the diameter or distance across
the flats (axial length > diameter or distance across the
flats)
KM-201.3 Bars and Bolting Materials. The thickness
for bars and bolting material shall be the diameter for
round bars, the lesser of the two cross‐section dimensions
for rectangular bars, and the distance across the flats for
hexagonal bars; or the length of a given bar, whichever is
less.
KM-201.4 Pipe. The thickness for pipe shall be the
nominal wall thickness.
KM-210 PROCEDURE FOR OBTAINING TEST
SPECIMENS AND COUPONS
For austenitic stainless steels and for nonferrous alloys,
the procedure for obtaining test specimen coupons shall
conform to the applicable material specification. These
materials are exempt from the requirements of KM-211.
KM-211 PRODUCT FORMS
KM-211.1 Plates.
(a) For thicknesses less than 2 in. (50 mm), specimens
shall be taken in accordance with the requirements of the
applicable material specification.
(b) For thicknesses 2 in. (50 mm) and greater, the cen-
terline of the test specimens shall be taken in accordance
with the requirements of the applicable material specifi-
cation, but not closer than T to any heat‐treated edge
and T/2 to the nearest plate surface.
(c) Where a separate test coupon is used to represent
the vessel material, it shall be of sufficient size to ensure
that the cooling rate of the region fromwhich the test spe-
cimens are removed represents the cooling rate of the
material at T/2 deep and at least T from any edge of
the product. Unless cooling rates applicable to the bulk
pieces or product are simulated in accordance with
KM-220, the dimensions of the coupon shall be not less
than 3T by 3T by T , where T is the maximum material
thickness.
KM-211.2 Forgings. The datum point, defined as the
midpoint of the gage length of tension test specimens or
the area under the notch of impact test specimens, shall
be located in accordance with one of the following meth-
ods. All testing shall be from integral prolongations of the
forging, except as permitted in (d), and shall be per-
formed after final heat treatment (see KT-111). In addi-
tion to the following, for quenched and tempered
materials, the location of the datum point shall be equal
to or farther from the nearest quenched surface than
any pressurized surface or area of significant loading is
from the quenched surface. The designer shall define
the datum point locations within the forging relative to
the rules of this Division.
(a) For forgings having a maximum quenched thickness
not exceeding 4 in. (100 mm), the datum points of the test
specimens shall be located in the forging or test forging at
mid‐thickness and at least 2T/3 (T is the maximum heat‐
treated thickness) from the quenched end surface or
nearest adjacent surfaces.

(b) For forgings having a maximum quenched thickness
in excess of 4 in. (100 mm), the datum points of the test
specimens shall be removed T /4 from the nearest
quenched surface and 2T /3 from the quenched end
surface or nearest adjacent surfaces. T/4 diameter or
thickness from a heat-treated end may be used for preci-
pitation hardening and age hardening materials listed in
Tables KM-400-2 and KM-400-2M (UNS Nos. S13800,
S15500, S17400, S17700, S45000, S45500, and S66286)
that have been air quenched after aging.
(c) For forgings that are contour shaped or machined to
essentially the finished product configuration prior to
heat treatment, find the interior location that has the
greatest distance to the nearest quenched surface. Desig-
nate this distance t/2. Test specimens shall be taken no
closer to any quenched surface than one half of this dis-
tance (1/4t location). The midlength of the specimen shall
be a minimum of t/2 from any second quenched surface.
(d)With prior approval of the Manufacturer, test speci-
mens may be taken from a separate test forging under the
conditions described in KM-231(d), or removed from a lo-
cation within the forging that has received substantially
the same reduction and type of hot working as the main
body of the forging for which the tests are being con-
ducted, if permitted by the material specification. The di-
mensional requirements specified in (a), (b), (c), or (e)
shall be met as applicable.
(e) For large forgings that require testing from each
end in accordance with KM-231(b) or KM-231(c), test
specimen locations according to (a), (b), (c), and (d)
may be designated at each end independently based on
the thickness at that end, provided at least one end repre-
sents the thickest dimension of the entire forging.
KM-211.3 Bars and Bolting Materials.
(a) For diameters or thicknesses less than 2 in.
(50 mm), the specimens shall be taken in accordance with
the requirements of the applicable material specification.

over, the datum point of the test specimen defined as
the midpoint of the gage length of a tension test specimen
or the area under the notch of the impact specimens shall
be located at T/4 from the outside rolled surface or dee-
per and no closer than 2T/3 diameter or thickness from a
heat‐treated end. T/4 diameter or thickness from a heat
treated end or deeper may be used for precipitation hard-
ening and age hardening steels that have been air
quenched after aging.

applicable material specification and at least T/4 from
any heat‐treated surface, where T is the maximum wall
thickness of the pipe, and with the ends of the specimens
no closer than T from a heat‐treated end of the pipe. Test
specimens shall be removed from integral prolongations
from the pipe after completion of all heat treatment and
forming operations.
KM-212 CHARPY IMPACT SPECIMENS
KM-212.1 Bolting Materials.
(a) Charpy V‐notch impact test specimens shall be the
standard 10 mm × 10 mm size and shall be oriented par-
allel to the axis of the bolt.
(b)Where Charpy V‐notch impacttesting is to be con-
ducted and bolt diameter does not permit specimens in
accordance with (a), subsize specimens may be used. Test
temperature shall be reduced in accordance with Table
KM-212.
(c) Where bolt diameter or length does not permit spe-
cimens in accordance with (a) or (b), impact testing is not
required.

als, Other Than Bolting, Not Containing Welds.
(a) The test coupons for Charpy specimens shall be or-
iented such that their major axes lie transverse to the di-
rection of maximum elongation during rolling or to the
direction of major working during forging. Examples of
acceptable Charpy V‐notch impact specimen orientations
removed from plate and pipe are shown in Figure
KM-212 illustrations (a) and (b), respectively. Since the
direction of major working in a forging can vary signifi-
cantly depending upon its shape and the forging method
used, a single, representative example of an acceptable
Charpy specimen removed from such a forging cannot
be shown. Corners of Charpy specimens parallel to and

KM-220 PROCEDURE FOR HEAT TREATING
SEPARATE TEST SPECIMENS
When metal products are to be heat treated and test
specimens representing those products are removed
prior to heat treatment, the test specimens shall be cooled
at a rate similar to and no faster than the main body of the
product. This rule shall apply for specimens taken directly
from the product as well as those taken from separate test
coupons representing the product. The following general
techniques may be applied to all product forms, test spe-
cimens, or test coupons representing the product.
(a) Any procedure may be applied that can be demon-
strated to produce a cooling rate in the test specimen that
matches the cooling rate of the main body of the product
at the region midway between mid‐thickness and the sur-
face (T/4) and no nearer to any heat‐treated edge than a
distance equal to the nominal thickness being cooled (T).
The cooling rate of the test specimen shall replicate that
of the actual part within a temperature of 25°F (14°C)
at any given instant, and any given temperature shall be
attained in both the actual part and test specimen within
20 sec at all temperatures after cooling begins from the
heat treating temperature. Cooling rate can be deter-
mined by any method agreed upon between the manufac-
turer and purchaser, and can include, but is not limited to,
theoretical calculations, experimental procedures, dupli-
cate test forgings, or any combination thereof.
(b) Faster cooling rates at product edges may be com-
pensated for by
(1) taking the test specimens at least T from a
quench edge, where T equals the product thickness
(2) attaching a similar alloy pad at least T wide by a
partial penetration weld to the product edge where speci-
mens are to be removed
(3) using thermal barriers or insulation at the pro-
duct edge where specimens are to be removed
(c) If cooling rate data for the product and cooling rate‐
control devices for the test specimens are available, the
test specimens may be heat treated in the device to repre-
sent the product provided that the provisions of (a) are
met.
(d)When the material is clad or weld deposit overlaid
by the producer prior to heat treatment, the full thickness
samples shall be clad or weld deposit overlaid before such
heat treatments.
KM-230 MECHANICAL TESTING
REQUIREMENTS
(a) For mater ia ls l i s ted in Tables KM-400-1 ,
KM-400-1M, KM-400-2, KM-400-2M, KM-400-3, and
KM-400-3M, tension and Charpy V‐notch impact tests
shall be conducted on representative samples of all mate-
rials used in the construction of pressure vessels, except
that impact tests specified in Tables KM-234.2(a) and
KM-234.2(b) are not required for nuts and washers,

GENERAL NOTE: The Charpy impact specimen notch orientation codes shown are in accordancewith ASTM E1823, Annex A2.
NOTES:
(1) For plate greater than 2.2 in. (55 mm) in thickness, short transverse (S‐T orientation) Charpy V‐notch impact specimens may also be used.
(2) Corners of the Charpy specimens may follow the contour of the component within the dimension limits shown.
(3) This Figure illustrates how an acceptable transverse Charpy specimen can be obtained from a cylindrical pipe too small for a full length
standard specimen in accordance with ASME SA-370. The corners of longitudinal specimens parallel to and on the side opposite the notch
may also be as shown.
(4) The transverse Charpy V‐notch specimen orientation for pipe shall be as shown in illustration (b‐1); either notch orientation (C‐R or C‐L) is
acceptable. If the transverse orientation shown in illustration (b‐1) cannot be accommodated by the pipe geometry, then the orientation
shall be as shown in illustration (b‐2). If the alternate transverse orientation shown in illustration (b‐2) cannot be accommodated by the
pipe geometry, then the orientation shall be as shown in illustration (b‐3); either notch orientation (L‐R or L‐C) is acceptable.

KM-240 HEAT TREATMENT
CERTIFICATION/VERIFICATION
TESTS FOR FABRICATED
COMPONENTS
Tests shall be made to verify that all heat treatments
(i.e., quenching and tempering, solution annealing, aging,
and any other subsequent thermal treatments that affect
the material properties) as applicable have produced the
required properties. Where verification tests shall be
made from test specimens representative of the section
being heat treated, the position and method of attachment
of test coupons shall most nearly represent the entire
item, taking into account its size and shape in accordance
with testing requirements of the material specification.
The requirements of KM-243 shall also apply.
KM-241 CERTIFICATION TEST PROCEDURE
(a) A sufficient number of test coupons to meet the re-
quirements of KM-243 shall be provided from each lot of
material in each vessel. These shall be quenched with the
vessel or vessel component.If material from each lot is
welded prior to heat treatment to material from the same
or different lots in the part to be quenched, the test cou-
pon shall be so proportioned that tensile and impact spe-
cimens may be taken from the same locations relative to
thickness as are required by the applicable material spe-
cifications. Weld metal specimens shall be taken from the
same locations relative to thickness as are required by the
material specifications for plates used in the component
to be treated. If desired, the effect of this distance may
be achieved by temporary attachment of suitable thermal
buffers. The effectiveness of such buffers shall be demon-
strated by tests.

(b) In cases where the test coupon is not attached to the
part being treated, it shall be quenched from the same
heat treatment charge and under the same conditions as
the part which it represents. It shall be so proportioned
that test specimens may be taken from the locations pre-
scribed in (a).
KM-242 TEMPERING
KM-242.1 Attached Test Coupons. The test coupons
shall remain attached to the vessel or vessel component
during tempering, except that any thermal buffers may
be removed after quenching. After the tempering opera-
tion and after removal from the component, the coupon
shall be subjected to the same thermal treatment(s), if
any, to which the vessel or vessel component will be later
subjected. The holding time at temperature shall not be
less than that applied to the vessel or vessel component
(except that the total time at each temperature may be ap-
plied in one heating cycle) and the cooling rate shall not
be faster.
KM-242.2 Separate Test Coupons. The coupons that
are quenched separately, as described in KM-241(b), shall
be tempered similarly and simultaneously with the vessel
or component which they represent. The conditions for
subjecting the test coupons to subsequent thermal treat-
ment(s) shall be as described in KM-242.1.
KM-243 NUMBER OF TESTS
One tensile test and one impact test, consisting of three
impact test specimens, shall be made on material from
coupons representing each lot of material in each vessel
or vessel component heat treated. A lot is defined as ma-
terial from the same heat, heat treated simultaneously
and having thicknesses within ±20% or 1/2 in. (13 mm)
of nominal thickness, whichever is smaller.
(a) Coupons not containing welds shall meet the com-
plete tensile requirements of the material specification
and impact requirements of this Part.
(b) Coupons containing weld metal shall be tested
across the weld and shall meet the required mechanical
property requirements of the material specification; in
addition, the minimum impact requirements shall be
met by samples with notches in the weld metal. The form
and dimension of the tensile test specimen shall conform
to Section IX, Figure QW-462.1(a) or Figure QW-462.1(d).
Charpy impact testing shall be in accordance with the re-
quirements of Article KT-2.
KM-250 SUPPLEMENTARY TOUGHNESS
REQUIREMENTS FOR
PRESSURE-RETAINING
COMPONENT MATERIALS
Where a fracture mechanics evaluation in accordance
with Article KD-4 is to be conducted, a value of KIc is re-
quired for the analysis. The designer shall specify the
minimum value of KI c required, the number of tests to
be performed, and shall indicate which of the following
methods are to be used to verify that the material meets
this value.
The orientation of the direction of crack propagation
for all test coupons shall be the same as the direction of
crack propagation expected in the fracture mechanics
analysis conducted in accordance with Article KD-4. Var-
iation of fracture toughness through the thickness of a
component shall be considered to ensure the toughness
used in Article KD-4 is representative of the material at
the location being considered.
KM-251 CHARPY V-NOTCH IMPACT TESTING
The designer may require that the pressure-retaining
component meet minimum Charpy V‐notch absorbed en-
ergy values that are greater than those specified in
KM-234.2 in order to verify compliance with the mini-
mum KI c value. If supplemental impact testing is con-
ducted, it shall be performed in accordance with SA-370
and be conducted at a temperature not exceeding the im-
pact test temperature specified in KM-234.1. It shall be
the designer’s responsibility to determine and specify
the appropriate KIc–CVN conversion equation, in compli-
ance with API 579-1/ASME FFS-1, to be used to ascertain
the Charpy V-notch acceptance criterion.
KM-252 CTOD FRACTURE TOUGHNESS TESTING
The designer may require that CTOD (crack tip opening
displacement) testing of the high pressure-retaining com-
ponent be conducted to verify compliance with the mini-
mum KI c value. If CTOD testing is required, it shall be
performed in accordance with ASTM E1290, and be con-
ducted ata temperature not exceeding the impact test
temperature specified in KM-234.1. The temperature re-
duction values given in Table KM-212 do not apply. It
shall be the designer’s responsibility to determine and
specify the appropriate KIc–CTOD conversion equation,
in compliance with API 579-1/ASME FFS-1, to be used
to ascertain the CTOD acceptance criterion.
KM-253 J Ic FRACTURE TOUGHNESS TESTING
The designer may require that J I c testing of the
pressure-retaining component be conducted to verify
compliance with the minimum KIc value. If J I c testing is
required, it shall be performed in accordance with ASTM
E1820 and shall be conducted at a temperature not ex-
ceeding the impact test temperature specified in
KM-234.1. The temperature reduction values given in
Table KM-212 do not apply. It shall be the designer’s re-
sponsibility to determine and specify the appropriate
KIc–JIc conversion equation, in compliance with API
579-1/ASME FFS-1, to be used to ascertain the J I c accep-
tance criterion.

KM-254 KIc FRACTURE TOUGHNESS TESTING
The designer may, at his option, require that direct KIc
testing of the pressure-retaining component be con-
ducted to verify compliance with the specified minimum
KIc value. If such testing is required, it shall be performed
in accordance with ASTM E399 and shall be conducted at
a temperature not exceeding the impact test temperature
specified in KM-234.1. The temperature reduction values
given in Table KM-212 do not apply.
KM-260 RETESTS
KM-261 GENERAL RETEST REQUIREMENTS
The following retest requirements apply to tension,
Charpy V‐notch impact, and CTOD, JIc, and KI c fracture
toughness tests.
(a) If any test specimen fails to meet the applicable ac-
ceptance criteria for mechanical reasons, such as test
equipment malfunction or improper specimen prepara-
tion, the results may be discarded and another represen-
tative specimen may be substituted.
(b) If any test specimen fails to meet the applicable ac-
ceptance criteria for nonmechanical reasons, two repre-
sentative specimens as close to the original specimen
location as possible may be selected for retesting without
reheat treatment, provided the failure was not caused by
preexisting material defects such as ruptures, flakes, or
cracks. Both of these specimens shall meet the applicable
acceptance criteria (see KM-262 for Charpy V‐notch im-
pact retests).
(c) Only one retesting is permitted. If the material fails
the retest, it may be retempered or reheat treated, as
necessary.
KM-262 SPECIAL CHARPY V-NOTCH IMPACT
RETEST REQUIREMENTS
(a) A Charpy V‐notch impact retest is permitted if the
average absorbed energy value meets the applicable ac-
ceptance criteria but the absorbed energy value for one
specimen is below the specified minimum for individual
specimens. The retesting shall consist of two representa-
tive impact specimens removed from a location adjacent
to and on either side, if possible, of the original specimen
location. Each of the retest specimens shall exhibit an ab-
sorbed energy value equal to or greater than the mini-
mum average value.
(b) Only one retesting is permitted. If the material fails
the retest, it may be retempered or reheat treated, as
necessary.
KM-270 NOTCH TENSILE TESTING
PROCEDURE AND ACCEPTANCE
CRITERION
Material listed in Table KM-400-4 or Table KM-400-4M
shall be qualified by the following notch tensile test for T6
or T651 temper:
(a) The Sharp‐Notch Strength/Yield Strength Ratio
shall be determined using the ASTM E338 or ASTM
E602 test method. Specimens shall be cut from a produc-
tion vessel. Two specimens from a production vessel shall
be tested to qualify a single heat of material. The samples
shall be obtained from the production vessel after all
forming and heat treating is completed.
(b) The geometry of the specimen shall meet the di-
mensional requirement of ASTM E338, paragraph 6,
Figure 3 or ASTM E602, Figure 1. The specimen shall be
cut such that the longitudinal axis of the production vessel
is parallel to the long axis of the specimen. The following
exemptions to the dimensional requirements of the above
specimens may be applied:
(1) For ASTM E338 specimen, the test section width
less than 2 in. (50 mm) may be used; however, the ratio of
the notch depth to specimen net ligament width shall not
be less than 0.25. The specimen thickness limitation in the
test section need not be satisfied.
(2) For ASTM E602 specimen, the test section dia-
meter less than 0.5 in. (12.5 mm) may be used; however,
the ratio of notch depth to the specimen net ligament dia-
meter shall not be less than 0.25.
(c) The tensile test methods in ASTM B557 shall be
used in lieu of ASTM E8 where specified in ASTM E338
and ASTM E602.

GENERAL NOTES:
(a) The following abbreviation is used: Smls. = Seamless.
(b) The P-Nos. and Group Nos. listed for some of these materials are for information only. For welded construction in this Division, Section IX, Table QW/QB-422 shall be consulted for
P-Nos. and Group Nos.
NOTES:
(1) This material is permitted only in wire form when used for wire‐wound vessels and wire‐wound frames as described in Article KD-9.
(2) Strength values listed in Section II, Part D, Subpart 1, Table Y-1 for intermediate thickness may be interpolated.
(3) The maximum nominal plate thickness shall not exceed 11/4 in. (32 mm).
(4) The minimum tempering temperature shall be 800°F (425°C).
(5) The yield strength values listed in Section II, Part D, Subpart 1, Table Y-1 apply to liquid quenched and tempered materials only.
(6) Section IX, QW-250 Welding Variables, QW‐404.12, QW‐406.3, QW‐407.2, and QW‐409.1 shall also apply to this material. These variables shall be applied in accordance with the
rules for welding of Part KF.
(7) Welding is not permitted when carbon content exceeds 0.35% by ladle analysis except as permitted in Article KF-7.
(8) The nominal wall thickness of the cylindrical shell of vessels constructed of SA-372 Grade J, Class 110 material shall not exceed 2 in. (50 mm).
(9) The maximum nominal plate thickness shall not exceed 6.00 in. (150 mm) for Grade E or 4.00 in. (100 mm) for Grade P.
(10) This material is permitted only when used as an inner layer in a vessel whose design meets the leak‐before‐burst criteria of KD-141.
(11) The maximum nominal plate thickness shall not exceed 0.58 in. (15 mm).
(12) The maximum nominal plate thickness shall not exceed 2.50 in. (64 mm).
(13) No welding is permitted on this material.
(14) Caution is advised when using this material above 700°F (375°C). After exposure to temperatures above 700°F (375°C), this material may exhibit temper embrittlement and stress
relaxation effects. The designer shall consider these effects and their influence on the vessel.
(15) When this material is used in welded construction, the following additional requirements apply:

Table KM-400-1
Carbon and Low Alloy Steels (Cont'd)
NOTES (CONT'D):
(a) In fulfilling the requirements of Articles KT-1 and KT-2, sufficient tensile tests shall be made to represent postweld heat treatment at both the minimum and maximum times
at temperature, and impact tests shall be made to represent the minimum time at temperature. The results of the tensile tests shall meet the tensile requirements of the material
specification. The number and orientation of the impact specimens, the testing temperature, and the acceptance criteria shall meet the impact test requirements of Part KM.
(b)Welding procedure qualification tensile tests shall meet both the minimum and maximum tensile strength requirements of the material specification.
(c) Each heat or lot of consumable welding electrodes and each heat or lot of filler wire and flux combination shall be tested to meet the requirements of (a) above.
(16) Caution is advised when using these materials as they are more susceptible than lower strength materials to environmental stress corrosion cracking and/or embrittlement due to
hydrogen exposure. This susceptibility increases as yield strength increases. The designer shall consider these effects and their influence on the vessel. See Section II, Part D, Non-
mandatory Appendix A, A‐330.
(17) These materials shall not be used for applications when the material, when loaded, is in contact with water or an aqueous environment.
(a) These materials are permitted if the material is protected from contact by water or an aqueous environment.
(b)This restriction does not apply to components that are in hydrostatic compression during all loading cycles. Hydrostatic compression is assumed to exist if the sum of the three
principal stresses is negative (compressive) at all locations within the component.
(c) This restriction does not apply to inner layers in a vessel whose design meets the leak-before-burst criteria of KD-141.
(18) The actual measured yield strength for these materials shall not be greater than 25 ksi (172 MPa) above the minimum specified value.
(19) These wire materials are suitable only for use in special closure parts designed in accordance with Article KD-6, for which it is impractical or impossible to obtain yield strength data.
The materials shall not be used for fabrication of other pressure-retaining components, such as bolting, wire-wound vessels, or wire-wound frames.
(20) For these wire materials, the value shown in the ”Thickness” column is the wire diameter. The wire may be reshaped for final use from a round to some other cross section, provided
the processing does not adversely affect the tensile strength of the material.
(21) Tensile strength values for intermediate diameters may be interpolated. The values at intermediate diameters shall be rounded to the same number of decimal places as the value at
the lesser diameter between which values are being interpolated. The rounding rule is: when the next digit beyond the last place to be retained is less than 5, retain unchanged the
digit in the last place retained; when the digit next beyond the last place to be retained is 5 or greater, increase by 1 the digit in the last place retained.
(22) These wire materials have maximum tensile strength requirements. See Section II, Part A, SA-231 or SA-232, as applicable.
(23) Welding of this material by the electroslag or electrogas process is not permitted. Except for local heating such as cutting and welding, heating of this material above 1,200°F (650°C)
during fabrication is also not permitted.
(24) This material is permitted only when used in the fabrication of external yokes.

GENERAL NOTES:
(a) The following abbreviation is used: Smls. = Seamless.
(b)The P-Nos. and Group Nos. listed for some of these materials are for information only. For welded construction in this Division, Section IX, Table QW/QB-422 shall be consulted for
P-Nos. and Group Nos.
NOTES:
(1) This material is permitted only in wire form when used for wire‐wound vessels and wire‐wound frames as described in Article KD-9.
(2) Strength values listed in Section II, Part D, Subpart 1, Table Y-1 for intermediate thickness may be interpolated.
(3) The maximum nominal plate thickness shall not exceed 11/4 in. (32 mm).
(4) The minimum tempering temperature shall be 800°F (425°C).
(5) The yield strength values listed in Section II, Part D, Subpart 1, Table Y-1 apply to liquid quenched and tempered materials only.
(6) Section IX, QW-250 Welding Variables, QW‐404.12, QW‐406.3, QW‐407.2, and QW‐409.1 shall also apply to this material. These variables shall be applied in accordance with the
rules for welding of Part KF.
(7) Welding is not permitted when carbon content exceeds 0.35% by ladle analysis except as permitted in Article KF-7.
(8) The nominal wall thickness of the cylindrical shell of vessels constructed of SA-372 Grade J, Class 110 material shall not exceed 2 in. (50 mm).
(9) The maximum nominal plate thickness shall not exceed 6.00 in. (150 mm) for Grade E or 4.00 in. (100 mm) for Grade P.
(10) This material is permitted only when used as an inner layer in a vessel whose design meets the leak‐before‐burst criteria of KD-141.
(11) The maximum nominal plate thickness shall not exceed 0.58 in. (15 mm).
(12) The maximum nominal plate thickness shall not exceed 2.50 in. (64 mm).
(13) No welding is permitted on this material.
(14) Caution is advised when using this material above 700°F (375°C). After exposure to temperatures above 700°F (375°C), this material may exhibit temper embrittlement and stress
relaxation effects. The designer shall consider these effects and their influence on the vessel.
(15) When this material is used in welded construction, the following additional requirements apply:
(a) In fulfilling the requirements of Articles KT-1 and KT-2, sufficient tensile tests shall be made to represent postweld heat treatment at both the minimum and maximum times
at temperature, and impact tests shall be made to represent the minimum time at temperature. The results of the tensile tests shall meet the tensile requirements of the material
specification. The number and orientation of the impact specimens, the testing temperature, and the acceptance criteria shall meet the impact test requirements of Part KM.
(b)Welding procedure qualification tensile tests shall meet both the minimum and maximum tensile strength requirements of the material specification.
(c) Each heat or lot of consumable welding electrodes and each heat or lot of filler wire and flux combination shall be tested to meet the requirements of (a) above.
(16) Caution is advised when using these materials as they are more susceptible than lower strength materials to environmental stress corrosion cracking and/or embrittlement due to
hydrogen exposure. This susceptibility increases as yield strength increases. The designer shall consider these effects and their influence on the vessel. See Section II, Part D, Non-
mandatory Appendix A, A‐330.

Table KM-400-1M
Carbon and Low Alloy Steels (Metric) (Cont'd)
NOTES (CONT'D):
(17) These materials shall not be used for applications when the material, when loaded, is in contact with water or an aqueous environment.
(a) These materials are permitted if the material is protected from contact by water or an aqueous environment.
(b) This restriction does not apply to components that are in hydrostatic compression during all loading cycles. Hydrostatic compression is assumed to exist if the sum of the three
principal stresses is negative (compressive) at all locations within the component.
(c) This restriction does not apply to inner layers in a vessel whose design meets the leak-before-burst criteria of KD-141.
(18) The actual measured yield strength for these materials shall not be greater than 25 ksi (172 MPa) above the minimum specified value.
(19) These wire materials are suitable only for use in special closure parts designed in accordance with Article KD-6, for which it is impractical or impossible to obtain yield strength data.
The materials shall not be used for fabrication of other pressure-retaining components, such as bolting, wire-wound vessels, or wire-wound frames.
(20) For these wire materials, the value shown in the ”Thickness” column is the wire diameter. The wire may be reshaped for final use from a round to some other cross section, provided
the processing does not adversely affect the tensile strength of the material.
(21) Tensile strength values for intermediate diameters may be interpolated. The values at intermediate diameters shall be rounded to the same number of decimal places as the value at
the lesser diameter between which values are being interpolated. The rounding rule is: when the next digit beyond the last place to be retained is less than 5, retain unchanged the
digit in the last place retained; when the digit next beyond the last place to be retained is 5 or greater, increase by 1 the digit in the last place retained.
(22) These wire materials have maximum tensile strength requirements. See Section II, Part A, SA-231 or SA-232, as applicable.
(23) Welding of this material by the electroslag or electrogas process is not permitted. Except for local heating such as cutting and welding, heating of this material above 1,200°F (650°C)
during fabrication is also not permitted.
(24) This material is permitted only when used in the fabrication of external yokes.
