Bibliography

Specifies the grades and the corresponding requirements for ausferritic spheroidal graphite cast irons. Defines 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, and samples cut from a casting. Also specifies two grades by a classification as a function of hardness.
