本部分代替ＧＢ／Ｔ５６８６．５—１９８８、ＧＢ／Ｔ５６８６．６—１９８８、ＧＢ／Ｔ７７３０．５—２０００、ＧＢ／Ｔ７７３０．６—１９８８、ＧＢ／Ｔ７７３０．７—１９８８、ＧＢ／Ｔ８６５４．８—１９８８。本部分是对ＧＢ／Ｔ５６８６．５—１９８８《锰硅合金化学分析方法　红外线吸收法测定碳量》、ＧＢ／Ｔ５６８６．６—１９８８《锰硅合金化学分析方法　气体容量法测定碳量》、ＧＢ／Ｔ７７３０．５—２０００《锰铁及高炉锰铁化学分析方法　红外线吸收法测定碳量》、ＧＢ／Ｔ７７３０．６—１９８８《锰铁及高炉锰铁化学分析方法　气体容量法测定碳量》、ＧＢ／Ｔ７７３０．７—１９８８《锰铁及高炉锰铁化学分析方法　重量法测定碳量》、ＧＢ／Ｔ８６５４．８—１９８８《金属锰化学分析方法　红外线吸收法测定碳量》的整合修订。本部分规定了红外线吸收法、气体容量法、重量法和库伦法测定锰硅合金、锰铁、高炉锰铁、氮化锰铁、金属锰和电解金属锰的碳含量。本部分适用于锰硅合金、锰铁、氮化锰铁金属锰和电解金属锰中碳含量的测定。 本部分与ＧＢ／Ｔ５６８６．５—１９８８和ＧＢ／Ｔ７７３０．５—２０００及ＧＢ／Ｔ８６５４．８—１９８８比较，其主要变化如下：
———方法适用范围规定为锰硅合金、锰铁、氮化锰铁和金属锰；
———锰硅合金中助熔剂纯铁的量由０．８００ｇ调整为０．４００ｇ；
———锰铁、氮化锰铁和金属锰的助熔剂统一为０．３００ｇ锡＋１．８００ｇ钨。
