本部分代替ＧＢ／Ｔ３６５４．６—１９８３和ＧＢ／Ｔ３６５４．７—１９８３。　本部分是对ＧＢ／Ｔ３６５４．６—１９８３《铌铁化学分析方法　燃烧碘量法测定硫量》和ＧＢ／Ｔ３６５４．７—１９８３《铌铁化学分析方法　次甲基蓝光度法测定硫量》的整合修订。本部分规定了用碘量法、次甲基蓝光度法和红外线吸收法测定铌铁中硫的含量。本部分适用于铌铁中硫含量的测定。碘量法的测定范围：0.035%-0.090%；次甲基蓝光度法的测定范围：0.0050%-0.035%；红外线吸收法的测定范围：0.0050%-0.090%。 本部分与ＧＢ／Ｔ３６５４．６—１９８３和ＧＢ／Ｔ３６５４．７—１９８３比较，主要进行的修订是：增加了红外线吸收法。
