1 Scope This European Standard defines the grades of grey cast iron and spheroidal graphite cast iron bars, which have been produced by the continuous casting process. This European Standard specifies the characterizing properties of grey cast iron bars by either:
a) the tensile strength measured on machined test pieces prepared from samples cut from the bars, or
b) the hardness measured on the bars.
If agreed by the manufacturer and the purchaser, the combination of both tensile strength from option a) and hardness from option b) may be specified. This European Standard specifies the characterizing properties of spheroidal graphite cast iron bars by the tensile strength measured on machined test pieces prepared from samples cut from the bars. This European Standard specifies 4 grades of grey cast iron and 14 grades of spheroidal graphite cast iron by a classification based on tensile strength and 4 grades of grey cast iron by a classification based on Brinell hardness. This European Standard specifies also the straightness of the bars. This European Standard does not cover technical delivery conditions for iron castings (see EN 1559‑...
