Scope

This document specifies a method for the determination of the moisture content of aluminium ores.

It applies to the samples taken from bulk aluminium ores, e.g. shipments and stockpiles.

Annex A specifies a method to be used when it is difficult to carry out sieving, crushing and dividing owing to the sample being adhesive or excessively wet. In this case the sample may be pre-dried until preparation can be conducted without any trouble and the pre-dried moisture content of a consignment can be determined by the procedure specified in Annex A. Annex B specifies methods of correction for sprayed water and/or rainfall. In the event of the consignment being subjected to rainfall and/or sprayed water to control dust emission, then the moisture content of the consignment can be corrected for this added water in accordance with Annex B.
