Amendments
This standard differs from DIN EN 1561: 1997-08 as follows
a the Introduction now includes further information regarding the combination of relevant wall thickness and
工一一
tensile strength, and the new system for designation of cast irons by numbers
O b)in Table 1 the minimum values for the tensile strength have been increased; they now apply to several
types of cast samples and three ranges of relevant wall thickness, 50 mm, 50 mm to 100 mm and
100 mm to 200 mm, alongside s 40 mm
C) in T able 2 the minimum Brinell hardness Values are now given for three ranges of relevant wall thickness
2 8 d) in Table 3, the size and type of samples have been modified relating to the relevant wall thickness
introduced
G e) Annex B"Comparison of grey cast iron material designations according to EN 1560 and ISO/TR 15931
has been included:
n Annex D, the anticipated values of tensile strength in casting have been increased for relevant wall
thickness> 50 mm
远
B g)in Annex E, examples to explain the relationship between wall thickness and mechanical properties have
been included
h) Annex F"Wedge penetration test"has been included
