BS ISO 17804:2020

This standard BS ISO 17804:2020 Founding. Ausferritic spheroidal graphite cast irons. Classification is classified in these ICS categories:

• 77.080.10 Irons

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 determined on machined test pieces prepared from:

1. separately cast samples, side-by-side cast or cast-on samples;

2. samples cut from a casting.

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