ISO 16918-1:2009规定了使用电感耦合等离子体质谱（ICP-MS）分析钢铁以测定锡、锑、铈、铅和铋的微量元素的方法。该方法适用于质量分数范围（μg/g）内的微量元素，如下所示: Sn:5μg/g至200μg/g；锑:1μg/g至200μg/g；Ce:10μg/g至1000μg/g；铅:0.5μg/g至100μg/g；Bi:从0.3μg/g到30μg/g。 附件B列出了使用ICP-MS测定微量元素时的干扰。

ISO 16918-1:2009 specifies a method for analysing steel and iron for the trace element determinations of Sn, Sb, Ce, Pb and Bi using inductively coupled plasma mass spectrometry (ICP-MS). The method is applicable for trace elements in the mass fraction ranges (μg/g) as follows: Sn: 5 μg/g to 200 μg/g; Sb: 1 μg/g to 200 μg/g; Ce: 10 μg/g to 1 000 μg/g; Pb: 0,5 μg/g to 100 μg/g; Bi: from 0,3 μg/g to 30 μg/g. Interferences in the determination of trace elements using ICP-MS are listed in Annex B.
