标准摘要
[中文适用范围]： 本文件规定了碳化硅基磨料颗粒和原油的化学分析。 适用于磨料磨粒表面杂质的测定，以及碳化硅含量大于95%（质量分数）时破碎原料中SiC含量的测定。 [外文原描述]： This document specifies the chemical analysis of silicon-carbide-based abrasive grains and crudes. It is applicable for the determination of the surface impurities of abrasives grains and the determination of the SiC content of crushed crude when the silicon carbide content is greater than 95 % (mass fraction).
