Abrasive grains and crude. Chemical analysis of silicon carbide Ingestion-build-67170 BS EN 15531-2 on SIRI1 Scope This International Standard covers 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 determining the SiC content of crushed crude when the silicon carbide content is greater than 95 % (m m). When the grain size of the silicon carbide is greater than or equal to 15 m, the determination of the loss on acid treatment is carried out
