NF EN ISO 21587-2

Chemical analysis of aluminosilicate refractory products (alternative to the X-ray fluorescence method) - Part 2 : wet chemical analysis

ISO 12677-2:2007 specifies traditional ("wet") 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 12677 gives alternatives to the X-ray fluorescence (XRF) method given in ISO 12677:2003.

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!
