This document specifies requirements for the preparation of fused beads for the chemical analysis of silicon carbide containing samples using X-ray fluorescence (XRF). The test methods described in this document are for silicon carbide and silicon carbide materials; however, the principles described can be applied to other reduced materials such as boron carbide, boron nitride, ferroalloys, sialons and silicon nitride using the modifications given in Annex A.
Fused cast beads of the samples prepared in accordance with this document are analysed in accordance with ISO 12677.st edition 2018-07 Preparation of silicon carbide and similar materials for analysis by ISO 12677 X-ray fluorescence (XRF) — Fused cast-bead method Préparation du carbure de silicium et de matériaux similaires en vue d'une analyse par fluorescence de rayons X (FRX) selon l'ISO 12677 — Méthode de la perle fondue Reference number ISO 16169:2018(E) ？ ISO 2018 ISO 16169:2018(E) COPYRIGHT
