标准摘要
[中文适用范围]： 本文件规定了测定钢和铸铁中硅含量的重量分析法。 该方法适用于0.10%（质量分数）和5.0%（质量分数）之间的硅含量。 注：对于含有钼、铌、钽、钛、钨、锆或高含量铬的样品，其结果不如非合金基体准确。 [外文原描述]： This document specifies a gravimetric method for the determination of the silicon content in steel and cast iron. The method is applicable to silicon contents between 0,10 % (mass fraction) and 5,0 % {mass fraction). NOTE For samples containing molybdenum, niobium, tantalum, titanium, tungsten, zirconium or high levels of chromium, the results are less accurate than for unalloyed matrixes.
