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.

Dieser Teil von ISO 21079 legt chemische Analysenverfahren fest für feuerfeste Erzeugnisse, die AZS (Aluminiumoxid, Zirkoniumoxid und Silicium(IV) oxid) (mit 5 % bis 45 % ZrO2) enthalten, und Rohstoffe, indem traditionelle (nasschemische) Verfahren angewendet werden.
Dieser Teil von ISO 21079 gilt nicht für feuerfeste Erzeugnisse, die auf MgO basieren.
Dieser Teil von ISO 21079 stellt eine Alternative zum Röntgenfluoreszenzverfahren (RFA) nach ISO 12677 dar
