Scope

This part of ISO 21079 specifies flame atomic absorption spectrophotometry (FAAS) and inductively coupled plasma emission spectrometry (ICP-AES) methods for the analysis of AZS (alumina, zirconia, and silica) refractory products (containing 5 % to 45 % of ZrO2) and raw materials. This part of ISO 21079 is not applicable to MgO-based refractories. This part of ISO 21079 gives alternatives to the X-ray fluorescence (XRF) method given in ISO 12677.
