適用范圍：This part of ISO 21079 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.The range of determination is given in Table 1.This part of ISO 21079 is not applicable to MgO-based refractories.NOTE This part of ISO 21079 gives alternatives to the X-ray fluorescence (XRF) method given in ISO 12677.
