Ehdotuksen tiedot

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. NOTE For further details, see EN 1559-1:2011 and EN 1559-3:2011.
