标准摘要
[中文适用范围]： 该方法包括在指定条件下从指定形状的漏斗中填充样品后，确定已知尺寸的接收器中的粉末质量。 该方法适用于自由流动的粉末，并且如果使用适当的漏斗，也适用于有结块倾向的粉末。 在粉末含有块的情况下，只有当这些块可以容易地分解而不破坏粉末颗粒时，该方法才适用。 [外文原描述]： The method consists in determining the mass of powder in receiver of known dimensions, after filling with the sample from a funnel of specified shape under specified conditions. The method is applicable to free flowing powders and, provided that an appropriate funnel is used, to powders which have a tendency to cake. In the case of powder containing lumps, the method is applicable only if these can be disintegrated readily without braeking down the particles of the powder.
