BS EN ISO 15378:2017 includes some technical changes concerning BS EN ISO 15378:2015

Methods of test for mortar for masonry - Determination of particle size distribution (by sieve analysis) PAS 15 BS EN 61334-3-21 applies only1 Scope 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
