Aluminium oxide primarily used for the production of aluminium — Method for the determination of tapped and untapped density

Oxyde d'aluminium principalement utilisé pour la production d'aluminium — Méthode de détermination de la masse volumique tassée ou inexploitée

Abstract / scope

ISO 18842:2015 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.

ISO 18842:2015 minimizes flow rate variations.
