标准范围

本文件规定了铁素体球墨铸铁的等级和相应要求。本文件规定了五个等级的铁素体球墨铸铁，其分类基于以下材料制备的机加工试样的机械性能:-单独铸造样品、并排铸造或铸造样品；-从铸件上切下的样品。本文件还规定了两个等级，根据硬度进行分类。

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:— separately cast samples, side-by-side cast or cast-on samples;— samples cut from a casting.This document also specifies two grades by a classification as a function of hardness.
