Aluminium oxide used for the production of aluminium — Determination of particles passing a 20 micr...
ISO 23202:2006 sets out a wet-sieving procedure for the determination of the percentage by mass of particles of smelter-grade alumina passing a 20 micrometre aperture sieve.
This procedure is applicable for aluminas with a minus 20 micrometre content up to 4 %.
