标准摘要
[中文适用范围]： 本国际标准规定了一种确定给定数量的冶炼厂级氧化铝通过重力流过精确构造的标准漏斗所需时间的方法。 注：设备和其他测试变量的变化可能会造成实验室间结果的显着差异。 （见表 A.1。 ） [外文原描述]： ISO 18843:2015 sets out a method for determining the amount of time taken for a given quantity of smelter-grade alumina to flow by gravity through a precisely constructed standard funnel. NOTE Variations in the apparatus and other test variables can create significant inter-laboratory differences in results. (See Table A.1.)
英文名称Aluminium oxide primarily used for the production of aluminium — Method for the determination of flow time
