本部分规定了钽铌中 碳量和硫量的测定。本部分适用于钽铌 碳量和硫量的测定。测定范围：C：0.0006%~0.5%;S: 0.0006%~0.05%。本部分代替ＧＢ／Ｔ１５０７６．１２—１９９４《钽铌化学分析方法　碳量的测定》和ＧＢ／Ｔ１５０７６．８—１９９４钽铌化学分析方法　铌中硫量的测定》。
本部分与ＧＢ／Ｔ１５０７６．１２—１９９４和ＧＢ／Ｔ１５０７６．８—１９９４相比，主要有如下变动：
———扩大了测定范围：碳的测定范围由０．００１％～０．５％修改为０．０００６％～０．５％；硫的测定范围由０．００５％～０．０５％修改为０．０００６％～０．０５％；
———改变了测定方法；
———补充了精密度与质量保证和控制条款；
———对文本格式进行了重新编辑。
