Aluminium oxide used for the production of aluminium. Determination of particles passing a 20 micrometre aperture sieve Ingestion-build-177197 Visibility-enhancement systems like video-camera aids1 Scope This International Standard sets out a wet sieving procedure for the determination of the percentage by mass of particles of smelter grade alumina passing a 20 m aperture sieve. This procedure is applicable for aluminas with a 20 m content up to 4 %.
