Chemical analysis of aluminosilicate refractory products (alternative to the X-ray fluorescence method). Inductively coupled plasma and atomic absorption spectrometry methods | Status: Confirmed, Current

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.
