标准摘要
[中文适用范围]： 本文件规定了用硫氰酸盐分光光度法测定钢铁中钼含量的方法。该方法适用于钼质量分数在 0.005% 至 0.125% 之间的物质。如果钒和钨的含量导致 V/Mo 比大于 16 或 W/Mo 比大于 8，则它们会干扰测量。 [外文原描述]： This document specifies a thiocyanate spectrophotometric method for the determination of molybdenum contents in steel and iron. The method is applicable to molybdenum mass fractions between 0,005 % and 0,125 %. Vanadium and tungsten interfere with the measurement if, because of their contents, the V/Mo ratio is greater than 16 or the W/Mo ratio is greater than 8.
