Abstract
ISO 21079-2:2008 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.
ISO 21079-2:2008 is not applicable to MgO-based refractories.
ISO 21079-2:2008 gives alternatives to the X-ray fluorescence (XRF) method given in ISO 12677.
