Founding. Ausferritic spheroidal graphite ausferrite cast iron. Classification. | Status: Superseded, Withdrawn

1 Scope This International Standard defines the grades and the corresponding requirements for ausferritic spheroidal graphite cast irons. This International Standard specifies five grades of ausferritic spheroidal graphite cast iron by a classification based on mechanical properties measured on machined test pieces prepared from:

• — separately cast samples or cast-on samples;
• — samples cut from a casting.

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