Bibliography
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.
