Amendments This standard differs from DIN EN 12449:2012-07 as follows: a) the new material CuFe0,1Sn0,1P (CW12
6、5C) has been included; b) the elongation values for Cu-DHP (CW024A) in material condition R250 have been modified and are now given in the newly added Table 16; c) in Table 7, the iron and tin content for CuZn37Pb1 (CW605N) has been changed from 0,2 % to 0,3 %; d) the material number for alloy CuSi3
7、Zn2P, CW121C, has been replaced by CW124C.
