Methods of test for mortar for masonry - Determination of water vapour permeability of hardened rendering and plastering mortars Ingestion-build-489741 Scope This European Standard specifies a method for determining the steady state water vapour permeability of rendering and plastering mortars in accordance with prEN 998 1 at the upper and lower part of the hygroscopic range. The test method is applicable to mortars from which disc shaped specimens of uniform thickness between 10 mm and 30 mm can be made.
