内容简介

This part of ISO 20565 specifies methods for the chemical analysis of chrome-bearing refractory products andchrome-bearing raw materials, using traditional (“wet”) methods, ICP-AES spectrometry and FAASspectrometry. It covers apparatus, reagents, dissolution and determination of gravimetric silica.It is applicable in the ranges of determination given in Table 1.ISO 20565 provides alternatives to the X-ray fluorescence (XRF) method given in ISO 12677.
