标准摘要
[中文适用范围]： 本文件规定了测定钢中氮的分光光度法。 本方法适用于低合金钢中0.0006%～0.050%和高合金钢中0.010%～0.050%之间氮质量分数的测定。 该方法不适用于含有氮化硅或硅含量高于 0.6% 的样品。 [外文原描述]： This document specifies a spectrophotometric method for the determination of nitrogen in steel. The method is applicable to the determination of nitrogen mass fraction between 0,000 6 % and 0,050 % in low alloy steels and between 0,010 % and 0,050 % in high alloy steels. The method does not apply to samples containing silicon nitrides or having silicon contents higher than 0,6 %.
