ＧＢ／Ｔ４３２４《钨化学分析方法》分为２７个部分，本部分为ＧＢ／Ｔ４３２４的第１３部分。本部分代替ＧＢ／Ｔ４３２４．１３—１９８４《钨化学分析方法　乙二醛双（２羟基苯胺）光度法测定钙量》和
ＧＢ／Ｔ４３２４．１４—１９８４《钨化学分析方法　原子吸收光度法测定钙量》。本部分规定了钨粉、钨条、三氧化钨、蓝钨、紫钨、仲钨酸铵、偏钨酸铵中钙含量的测定方法。本部分同时也适用以上其测定，测定范围：0.0003%--0.050%。本部分与ＧＢ／Ｔ４３２４．１３—１９８４和ＧＢ／Ｔ４３２４．１４—１９８４相比主要变化如下：
———测定方法改为电感耦合等离子体原子发射光谱法，取消了乙二醛双（２羟基苯胺）分光光度法和原子吸收分光光度法；
———增加了前言、精密度及质量保证和控制内容。
