ISO 21079-1:2008规定了使用传统(“湿”)方法的AZS(氧化铝,氧化锆和二氧化硅)耐火材料(含有5%至45%的ZrO 2)和原料的化学分析方法,电感耦合等离子体原子发射(ICP-AE)光谱和火焰原子吸收(FAA)光谱法。它涵盖仪器,试剂和溶解方法。
ISO 21079-1:2008不适用于MgO基耐火材料。
ISO 21079-1:2008给出了ISO 12677中给出的X射线荧光(XRF)方法的替代方案
ISO 21079-1:2008 specifies methods for the chemical analysis of AZS (alumina, zirconia, and silica) refractory products (containing 5 % to 45 % of ZrO2) and raw materials, using traditional ("wet") methods, inductively coupled plasma atomic emission (ICP-AE) spectrometry and flame atomic absorption (FAA) spectrometry. It covers apparatus, reagents and dissolution methods.
ISO 21079-1:2008 is not applicable to MgO-based refractories.
ISO 21079-1:2008 gives alternatives to the X-ray fluorescence (XRF) method given in ISO 12677.
