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.
