1 Scope
This part of ISO 21587 specifies inductively coupled plasma/atomic emission (ICP/AE) spectrometry and flame atomic absorption (FAA) spectrometry methods for the chemical analysis of aluminosilicate refractory products and raw materials.
The methods are applicable to the determination of the following:
-
— silicon(IV) oxide (SiO2)
-
— aluminium oxide (Al2O3)
-
— iron(III) oxide (total iron oxide calculated as Fe2O3)
-
— titanium(IV) oxide (TiO2)
-
— manganese(II) oxide (MnO)
-
— calcium oxide (CaO)
-
— magnesium oxide (MgO)
-
— sodium oxide (Na2O)
-
— potassium oxide (K2O)
-
— chromium(III) oxide (Cr2O3)
-
— zirconium oxide (ZrO2)
-
— phosphorous(V) oxide (P2O5)
This part of ISO 21587 gives alternatives to the X-ray flluorescence (XRF) method given in ISO 12677:2003, Chemical analysis of refractory products by XRF — Fused cast bead method.
