标准摘要
[中文适用范围]： 本国际标准描述了主要用于铝生产的冶炼级氧化铝的振实和未振实堆积密度的测定方法。 已发现使用样品落入容器的方法对流速变化敏感，这是由氧化铝的物理性质引起的。 该国际标准最大限度地减少了流量变化。 [外文原描述]： ISO 18842:2015 describes methods for the determination of tapped and untapped bulk density of smelter grade aluminium oxide primarily used for the production of aluminium. Methods using the fall of sample into a receptacle have been found to be sensitive to flow rate variations, which are caused by physical properties of the aluminium oxide. ISO 18842:2015 minimizes flow rate variations.
英文名称Aluminium oxide primarily used for the production of aluminium — Method for the determination of tapped and untapped density
