ISO 439:2020 钢和铸铁 硅含量的测定 重量法

标准编号：ISO 439:2020

中文名称：钢和铸铁 硅含量的测定 重量法

英文名称：Steel and cast iron — Determination of silicon content — Gravimetric method

发布日期：2020-02

标准范围

本文件规定了测定钢和铸铁中硅含量的重量分析法。该方法适用于硅含量在0.10%（质量分数）和5.0%（质量分数）之间的情况。注:对于含有钼、铌、钽、钛、钨、锆或高水平铬的样品，结果不如非合金基体准确。

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.
