This International Standard sets out requirements for the sampling of aluminium ores from moving streams and stationary situations, including stopped-belt sampling, to provide gross samples for sample preparation. Stopped-belt sampling is the reference method for collecting ore samples against which other sampling procedures may be compared. Sampling from moving streams is the preferred method. Sampling from stationary situations should only be considered when sampling from moving streams is not possible. The procedures described in this International Standard for sampling from stationary situations merely minimize some of the sampling errors. Although this International Standard is intended to cover all aluminium ore sampling from moving streams, the procedures recommended may not be applicable in cases of extreme segregation, for example very wet ore due to its sticky nature, or very dry ore due to generation of dust. In such cases it may be necessary to revert to stopped-belt sampling.

This International Standard specifies a BPHA spectrophoto-metric method for the determination of the vanadium content of aluminium ores. It is applicable to ores containing between 0,005 % (m/m) and 0,4 % (m/m) of vanadium pentoxide.

This International Standard 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.
