This European Standard specifies two methods of determining the particle size distribution of dry mixed or non-hardened wet mixed mortars. The method of wet sieving is applicable to mortars containing normal weight aggregates and the method of dry sieving to
mortars containing lightweight aggregates.
This European Standard does not cover particle size distribution of separate aggregates, which should be determined in accordance with the test method described in European Standard EN 933, nor does it
cover mixes containing fibres which cannot be removed before sieving.
