Põhitekst
ISO 21079-3:2008 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. ISO 21079-3:2008 is not applicable to MgO-based refractories. ISO 21079-3:2008 gives alternatives to the X-ray fluorescence (XRF) method given in ISO 12677.
