Methods of test for mortar for masonry - Part 19: Determination of water vapour permeability of hardened rendering and plastering mortars
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.

Overview
EN 1015-19:1998/A1:2004 (CEN) specifies a laboratory method to determine the steady‑state water vapour permeability of hardened rendering and plastering mortars. The procedure targets mortars referenced in prEN 998‑1 and covers measurements at the upper and lower parts of the hygroscopic range. The test is applicable to disc‑shaped specimens of uniform thickness between 10 mm and 30 mm and provides a quantitative basis for assessing the vapour transport properties of mortars used in building envelopes.
Keywords: EN 1015-19, water vapour permeability, water vapor permeability, rendering mortars, plastering mortars, mortar testing methods, prEN 998-1.
Key Topics and Requirements
- Scope: Determination of steady‑state vapour permeability for hardened rendering and plaster mortars within the hygroscopic moisture range.
- Specimens: Disc-shaped samples with uniform thickness between 10–30 mm.
- Definitions: Adds formal symbols - t (specimen thickness, m) and W (water vapour permeability, kg·m⁻¹·s⁻¹·Pa⁻¹).
- Mass measurement: Required balance accuracy revised to 0.1 g (amendment to sub-clause 5.2).
- Thickness measurement: Instrument accuracy 0.2 mm; measure thickness at three places and use the mean specimen thickness for calculations.
- Calculation principle: Permeability is derived from steady mass flux through the specimen, the applied vapour pressure difference and the mean thickness (per the standard’s defined equations and notation).
- Amendment A1 (2004): Updates several sub‑clauses (4.2, 5.2, 5.9, 6.2, Clause 8) to clarify measurement practice and notation.
Applications
- Quality control and product development for rendering and plastering mortars.
- Hygrothermal performance assessment in building physics studies and moisture management of wall assemblies.
- Specification and compliance testing for manufacturers, independent testing laboratories, architects and façade engineers.
- Comparative testing for selection of mortars in renovations, historical building conservation and new construction where vapour permeability affects drying and condensation risk.
Who Uses This Standard
- Mortar and cement manufacturers
- Independent construction materials testing laboratories
- Building physicists and façade consultants
- Architects, specifiers and regulatory bodies concerned with moisture and indoor climate performance
Related Standards
