This European Standard specifies requirements for malleable cast iron used in the manufacture of castings. This standard specifies two groups of material, namely whiteheart malleable cast iron and blackheart malleable cast iron. Each group is represented by several grades of material. Classification is given on the basis of mechanical properties determined on separately cast test pieces. This standard specifies 0,2% proof stress values when required by the purchaser.This standard specifies Brinell hardness values when required by the purchaser. This standard does not cover chemical composition requirements.
