DIN EN ISO 20565-1-2009 含铬耐火材料产品和含铬原材料的化学分析(可选择X射线荧光法).第1部分:装置、试剂、重量分析硅石的溶解和测定
Chemical analysis of chrome-bearing refractory products and chrome-bearing raw materials (alternative to the X-ray fluorescence method) - Part 1: Apparatus, reagents, dissolution and determination of gravimetric silica (ISO 20565-1:2008); English version
This part of ISO 20565 specifies methods for the chemical analysis of chrome-bearing refractory products and
chrome-bearing raw materials, using traditional ("wet") methods, ICP-AES spectrometry and FAAS
spectrometry. 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.
