This document defines the grades and the corresponding requirements for ausferritic spheroidal graphite cast irons.

This document specifies five grades of ausferritic spheroidal graphite cast iron by a classification based on mechanical properties measured on machined test pieces prepared from cast samples. One grade also has additional but optional requirements for room temperature and notched-impact.

This document also specifies two grades by a classification as a function of hardness.

This document does not cover technical delivery conditions for iron castings.
