ISO 23202:2006规定了湿法筛分程序,用于测定通过20微米孔径筛的冶炼级氧化铝颗粒的质量百分比。
本程序适用于铝含量为-20微米,高达4%的铝。
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 %.
