《GB/T 15072.9-2008贵金属合金化学分析方法金合金中铟量的测定 EDTA络合返滴定法》由TC243（全国有色金属标准化技术委员会）归口，TC243SC5（全国有色金属标准化技术委员会贵金属分会）执行，主管部门为中国有色金属工业协会。
本标准规定了金合金中铟量的测定。本部分适用于ＡｕＮｉＩｎ合金中铟含量的测定。测定范围（质量分数）：７％～１０％。本部分代替ＧＢ／Ｔ１５０７２．９―１９９４《贵金属及其合金化学分析方法　金合金中铟量的测定》。
本部分与ＧＢ／Ｔ１５０７２．９―１９９４相比，主要有如下变动：
―――标准名称由ＧＢ／Ｔ１５０７２．９―１９９４《贵金属及其合金化学分析方法　金合金中铟量的测定》变更为《贵金属合金化学分析方法　金合金中铟量的测定　ＥＤＴＡ络合返滴定法》；
―――按新标准编写的要求对溶液的配制、浓度的表示等进行了修订；
―――将原标准范围ＡｕＮｉＩｎ９-８修改为本标准适用于ＡｕＮｉＩｎ合金中铟含量的测定；测定范围（质量分数）：７％～１０％；
―――按照ＧＢ／Ｔ２０００１．４―２００１格式要求重新编写。
