标准摘要
[中文适用范围]： 测定自由流堆积密度的原理在于将样品通过指定的漏斗倒入已知体积的指定容器中并称量容器中的内容物。 为了确定压实堆积密度，应在敲击体积计中敲击固定次数（通常为 300 次）后测量给定质量的产品的体积。 三张图显示了合适的装置。 [外文原描述]： The principle of the determination of the fee-flow bulk density consists in pouring a sample through a specified funnel into a specified receptacle of known volume and weighing the contents of the receptacle. In order to determine the compacted bulk density a volume of a given mass of the product shall be measured after a fixed number of taps (usually 300) in a tapping volumeter. Three figures show suitable apparatus.
