标准摘要
[中文适用范围]: 本部分ISO 20565规定了使用传统(“湿法”)方法、ICP-AES光谱法和FAAS光谱法对含铬耐火制品和含铬原材料进行化学分析的方法。它涵盖了仪器、试剂、溶解和重量法二氧化硅的测定。它适用于表1中给出的测定范围。ISO 20565提供了ISO 12677中给出的X射线荧光(XRF)方法的替代方案。表1列出了各成分的测定范围(质量百分比):SiO2 (0.5至10), Al2O3 (2至30), Fe2O3 (0.5至25), TiO2 (0.01至1), MnO (0.01至1), CaO (0.01至3), MgO (15至85), Na2O (0.01至1), K2O (0.01至1), Cr2O3 (2至60), ZrO2 (0.01至0.5), P2O5 (0.01至5), LOI (-0.5至5)。注:这些数值是在考虑了烧失量(LOI)之后的值。 [外文原描述]: ISO 20565-1:2008 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.
