Testing of ceramic raw and basic materials. Direct determination of mass fractions of impurities in powders and granules of silicon carbide by OES by DC arc excitation Ingestion-build-446801 Scope This European Standard describes the method for the analysis of mass fractions of the impurities Al, B, Ca, Cr, Cu, Fe, Mg, Ni, Ti, V and Zr in powder and grain shaped silicon carbide of ceramic raw and basic materials. This application can also be extended to other metallic elements and other similar non metallic powder and grain shaped materials such as carbides, nitrides, graphite, carbon blacks, cokes, carbon, as well as a number of

primarily due to the difficulties in obtaining adequate compaction

Maximum-permitted expanded uncertainties of measurement are also specified

Testing institutes

This will ensure that your products are of good quality and comply with the International Maritime Organization regulatory standards

Conservator

such as metal processing and welding

The test method is referred to as the compression-after-impact (CAI) test when used to determine the residual compression strength of an impacted plate

With BS EN 60335-2-88 you can ensure the safety of end consumers against injuries

a part of the BS EN 12020 series

ISO 6974-3 also helps you to evaluate the bias of the measurement process which can help you to identify the cause of the bias

Nitrate-base films are not covered by this International Standard
