DIN EN 15979
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; German version EN 15979:2011

Title (German)

Prüfung keramischer Roh- und Werkstoffe - Direkte Bestimmung der Massenanteile an Verunreinigungen in pulver- und kornförmigem Siliciumcarbid mittels OES und Anregung im Gleichstrombogen; Deutsche Fassung EN 15979:2011

Overview

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. The 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 further oxidic raw and basic materials after appropriate testing. The testing procedure is applicable to mass fractions of the impurities mentioned above from approximately 1 mg/kg up to approximately 3 000 mg/kg, after verification. In some cases it may be possible to extend the range up to 5 000 mg/kg depending on the main influencing parameters element, wavelength, arc parameter and sample weight.
The European Standard has been prepared by CEN/TC 187 "Refractory products and materials", the secretariat of which is held by BSI (United Kingdom). The responsible German committee is Working Committee NA 062-02-64 AA "Chemische Analyse von nichtoxidischen keramischen Roh- und Werkstoffen" ("Chemical analysis of non-oxidic ceramic raw and basic materials") at NMP.
