标准摘要
[中文适用范围]： 通过在分散剂的水溶液中筛分来定量分离63至16m范围内的颗粒。 筛子是方孔或圆孔电铸筛子，具体取决于其来源。 将每个筛分的级分干燥并称重。 [外文原描述]： The particles in the range of 63 to 16 m are quantitatively separated by sieving in an aqueous solution of a dispersing agent. The sieves are square-aperture or round-aperture electroformed sieves, depending on their origin. Each sieved fraction is dried and weighed.
英文名称Aluminium oxide primarily used for the production of aluminium — Determination of the fine particle size distribution (less than 60 mu/m) — Method using electroformed sieves
