1  Scope


This part of ISO 6506 specifies the method for the Brinell hardness test for metallic materials. It is

applicable to both fixed location and portable hardness testing machines.

For some specific materials and/or products, particular International Standards exist (e.g. ISO 4498)

and make reference to this International Standard.

国家标GB/T 231.2-2009《金属材料 布氏硬度试验》第1部分:试验方法

       本标准修改采用国际标准 ISO 6506-1:2005《金属材料 布氏硬度试验 第1部分:试验方法》(英文版)。

       本标准根据ISO 6506-1:2005重新起草,根据我国的实际情况,该标准在采用国际标准时进行了修改和补充。这些技术性差异用垂直单线标识在它们所涉及的条款的页边空白处。

       本标准结构和技术内容与ISO 6506-1:2005基本一致,根据我国情况在以下几方面进行了修改:

       —— 删去了国际标准的前言;

       —— “本国际标准”一词改为“本标准”

       —— 用小数点“.”代替作为小数点的“,”;

       —— 在规范性引用文件中删去了标准ISO4498;

       —— 在第6章中的6.1增加了试样表面粗糙度的建议;

       —— 对原ISO 6506-1:2005标准的附录C硬度值的测量不确定度进行了修改。
