《GB/T 20975.22-2008铝及铝合金化学分析方法第22部分：铍含量的测定依莱铬氰兰R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铍含量的测定方法。本部分适用于铝及铝合金中铍含量的测定。测定范围：0.00010%--0.40%。本部分代替GB/T 6987.22-2001《铝及铝合金化学分析方法　依莱铬氰兰Ｒ分光光度法测定铍量》。
本部分与GB/T 6987.22-2001相比主要变化如下：
―――增加了“８．１重复性”条款；
―――增加了“９质量保证与控制”条款；
―――根据重复性限数值对其原有允许差范围进行了修改，使二者数值相互匹配。
