《GB/T 20975.4-2008铝及铝合金化学分析方法 第4部分:铁含量的测定 邻二氮杂菲分光光度法》由TC243(全国有色金属标准化技术委员会)归口,TC243SC1(全国有色金属标准化技术委员会轻金属分会)执行,主管部门为中国有色金属工业协会。
本部分规定了铝及铝合金中铁含量的测定方法。本部分适用于铝及铝合金中铁含量的测定。测定范围:0.001%~3.50%。 本部分代替GB/T6987.4―2001《铝及铝合金化学分析方法 邻二氮杂菲分光光度法测定铁量》。
本部分与GB/T6987.4―2001相比主要变化如下:
―――增加了“重复性”和“质量保证与控制”条款;
―――根据重复性限试验的结果将>0.0050%~0.0075%的允许差由0.0007%调整为0.0010%;将>0.0075%~0.0100%的允许差由0.0010%调整为0.0015%。


This part specifies the determination method of iron content in aluminum and aluminum alloy.
