该方法包括在特定条件下从特定形状的漏斗中填充样品后，测定已知尺寸接收器中粉末的质量。该方法适用于自由流动的粉末，如果使用合适的漏斗，则适用于有结块倾向的粉末。对于含有团块的粉末，该方法仅适用于这些团块在不粉碎粉末颗粒的情况下易于分解的情况。

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.
