BS EN ISO 21079-2:2008

Chemical analysis of refractories containing alumina, zirconia, and silica. Refractories containing 5 percent to 45 percent of ZrO2 (alternative to the X-ray fluorescence method). Wet chemical analysis | Status: Current, Confirmed

1 Scope 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. 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.
