Addresses chemical analysis of abrasive grains or crude based on fused aluminium oxide. Applicable to commercially available products but not necessarily to products altered by use.

This International Standard deals with the chemical analysis of abrasive grains or crude based on fused aluminium oxide. It applies to commercially available products but not necessarily to products which have been altered by use. It includes the following determinations:

• Loss on ignition

• Silicon dioxide

• Iron oxide

• Titanium dioxide

• Calcium oxide

• Magnesium oxide

• Zirconium oxide

• Aluminium oxide

• Analysis by atomic absorption spectrometry
