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 %.

ISO 2496:2006 specifies the following four test methods for the determination of the hygroscopic moisture content of test samples:
Method 1 -- Gravimetric method;
Method 2 -- Karl Fischer volumetric method;
Method 3 -- Karl Fischer coulometric method;
Method 4 -- Mass-loss method.
Any of these methods is applicable wherever the analytical value of a chemical constituent is to be calculated to a…
