GB/T5121《铜及铜合金化学分析方法》共有27部分。本部分为第9部分。本方法规定了铜及铜合金中铁含量的测定方法。本方法适用于铜及铜合金中铁含量的测定。测定范围:0.0001%~0.0020%。 本部分代替GB/T5121.9—1996《铜及铜合金化学分析方法 铁量的测定》、GB/T13293.7—1991《高纯阴极铜化学分析方法 塞曼效应电热原子吸收光谱法测定铁、钴、铅量》。 本部分与GB/T5121.9—1996、GB/T13293.7—1991相比,主要变动如下:
———方法一是对GB/T13293.7—1991的修订,补充了质量保证和控制条款,增加了精密度条款
———方法二是对GB/T5121.9—1996中“第一篇 方法1 1,10二氮杂菲分光光度法”的修订,补充了质量保证和控制条款,增加了精密度条款;
———方法三是对GB/T5121.9—1996中“第二篇 方法2 重铬酸钾滴定法”的修订,补充了质量保证和控制条款,增加了精密度条款;
———增加了方法四,等同采用国际标准ISO4748:1984 《铜合金———铁量的测定———Na2EDTA 滴定法》。
