NF A32 - 201 1997 Standard for Ductile Cast Iron

We met the FGS degrees from Franch and Italy clients, but it is very difficult to find the standard NF A32-201 from internet. We found they are similar with China standard GB T1348 1998, so we modified the GB T1348 into NF A32 - 201 1997 according to our understanding. Therefore, the following main content is not real NF A32-201 standard. We just made it for your reference.

This standard is similar with the other standards for nodular iron such as ASTM A536 in USA, GB T1348 in China, KS D4302 in Korea, DIN 1693 in Germany and ISO 1083.
