DESCRIPTION
BS EN ISO 21079-3:2008
This standard BS EN ISO 21079-3:2008 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) is classified in these ICS categories:
- 71.040.40 Chemical analysis
- 81.080 Refractories
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.
