Abrasive grains and crude. Chemical analysis of silicon carbide1 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

they are presented in Clause 4 and Clause 5

This document is intended to be used in conjunction with the detail specification that is particular to each application

The object of this standard is to specify general requirements and to serve as the basis for particular standards
