EN 1563:2012
Overview of Changes • Addition of solid-solution strengthened ductile cast irons
• Mechanical Properties always in
dependence on the wall thickness
• No material grades by hardness
• New „side-by-side cast sample“
• Sample dimension in dependence of 
the relevant wall thickness
• New annexes
EN 1563:2012

Solid-solution strengthened GJS
•Up to now, only one family of material 
grades were defined: ferritic to pearlitic 
spheroidal graphite cast irons
•
•EN 1563:2012 introduces a new material 
family: solid-solution strengthened ferritic 
spheroidal graphite cast iron (cast iron with 
nodular graphite and a ferritic matrix, that is 
hardened through silicon)
•First international standard to establish 
high-silicon containing DCI ISO 1083:2004, 
in Annex A (normative): “Spheroidal 
graphite cast irons with high silicon content”
EN 1563:2012
Solid-solution strengthened GJS

•For the first time in a national standard a chemical analysis is 
recommended for ductile cast Iron.
•Appendix A describes informative possible chemical compositions, 
graphit structure, the iron matrix etc. 
EN 1563:2012
Spheroidal graphite cast irons – Relation between Brinell hardness 
and 0,2 % - proof strength
Annex A
• maximum pearlite content 5%
• maximum free cementite 1%
• up to 20% Form III especially 
in heavy walls acceptable
• higher Rp0,2/Rm-ratio
• changed strength/hardnessratio!
Higher proof strength at lower ardness!

•Up to now the mechanical properties are defined for 
separately cast samples and for cast-on samples.
• In EN 1563:2012 the mechanical properties of each family 
of material grades is defines in dependence on the wall 
thickness regardless of the type of sample used.
•Designation of the sample type
S – separately cast sample
U – cast-on sample
is omitted!
( C for samples cut from the casting is mantained)
•Three ranges of wall thickness are considered!
Dependence on the Wall Thickness

EN 1563:2012
Types of Cast Samples
Up to now, three types of cast samples were defined
• separately cast samples (sample, that is cast in a separate mold at the same 
time and under representative manufacturing conditions as the casting)
• cast-on samples (sample, that is cast attached to the casting)
• samples cut from the casting
EN 1563:2012 added a new type of cast sample
• side-by-side cast sample (sample, that is produced in the same mold as the 
casting using the same sprue)
Siempelkamp Giesserei, 2012 7/16
EN 1563:2012
• In the current version of the 
standard no dependence of the 
sample size from the relevant wall 
thickness of the casting is imposed
• In EN1563:2012 the size of the 
sample has to be chosen according 
to the relevant wall thickness in four 
ranges
• Relevant wall thickness: 
Wall thickness representative for the 
casting, defined for the 
determination of the cast samples to 
which the mechanical properties 
apply

Guidance Values for Hardness
Siempelkamp Giesserei, 2012 9/16
Up to now (EN 1563:1997) a designation of a 
sheroidal graphite cast iron grade by hardness 
was possible 
In EN1563:2012 the designation by 
hardness is omitted.
Guidance values for the hardness of the 
different material grades are given in 
Annex C.
EN 1563:2012
A - Additional information on solid-solution strengthened ferritic spheroidal graphite cast 
irons
B - Guidance values for mechanical properties measured on test pieces machined from 
samples cut from the castings
C - Guidance values for hardness
D - Nodularity
F - Fracture toughness, impact energy and ductility of spheroidal graphite cast irons
G - Sectioning procedure for cast samples
H - Comparison of spheroidal graphite cast iron material designations according to
EN 1560 and ISO/TR 15931
