标准摘要
[中文适用范围]： 本标准规定了电感耦合等离子体发射光谱法测定钢中铌含量的方法。 该方法适用于铌含量在0.005%至5%（质量分数）之间。 [外文原描述]： ISO 13899-2:2005 specifies a method for the determination of the niobium content in steel by means of inductively coupled plasma emission spectrometry. This method is applicable to niobium contents between 0,005 and 5 % (mass fraction).
英文名称Steel — Determination of Mo, Nb and W contents in alloyed steel — Inductively coupled plasma atomic emission spectrometric method — Part 2: Determination of Nb content
