Scope

This International Standard describes methods for the determination of tapped and untapped bulk density of smelter grade aluminium oxide primarily used for the production of aluminium. Methods using the fall of sample into a receptacle have been found to be sensitive to flow rate variations, which are caused by physical properties of the aluminium oxide. This International Standard minimizes flow rate variations.
