Sets out the methods for the sample preparation of smelter-grade alumina. The methods are suitable for dry, free-flowing aluminas.

This Guide gives methods for the sample preparation of smelter-grade alumina. It covers the reduction of a bulk sample between 2 kg and 20 kg to produce a sample that is suitable for chemical and physical analysis. The reduced sample produced will be representative of the initial bulk sample. The bulk sample is considered to be from one source.The methods are suitable for dry, free-flowing aluminas.As the moisture content will influence many physical analyses, the method aims to minimize the exposure of the sample to the atmosphere to avoid water absorption. For preparation of samples for moisture analysis on an ‘as received’ basis, refer to AS 2879.1.
