BS EN ISO 21587-3:2007

This standard BS EN ISO 21587-3:2007 Chemical analysis of aluminosilicate refractory products (alternative to the X-ray fluorescence method) is classified in these ICS categories:

• 81.080 Refractories

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.
