Analiza kimike te materialeve refraktare qe përmbajnë alumin, zircon dhe silicë - Materialet refraktare qe përmban 5 % deri ë 45 % të ZrO2 (alternative me metodën e fluoreshencës së rrezeve X) - Pjesa 3: Spektrofotometri e absorbimit atomik te flakes (FAAS) dhe shoqëruar me iduksion me spektrometrine e emetimit te plazmes (ICP -AES) (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) - Part 3: Flame atomic absorption spectrophotometry (FAAS) and inductively coupled plasma emission spectrometry (ICP -AES) (ISO 21079-3:2008)

Scope

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.
