scope:

This International Standard specifies a method for the determination of the apparent density of washing powders by measuring the mass of a given volume. The method is applicable to free flowing powders and, provided that an appropriate funnel is used, to powders which have a tendency to cake. The method is suitable for other substances in the form of powder or granules. In the case of powder containing lumps, the method is applicable only if these can be disintegrated readily without breaking down the particles of the powder.
