Conservation of cultural property. Test methods. Determination of water vapour permeability (δ_p) Ingestion-build-44616 Values stated in SI units1 Scope This European Standard specifies a method for determining the water vapour permeability (WVP) of porous inorganic materials used for and constituting cultural property. The method may be applied to porous inorganic materials either untreated or subjected to any treatment or ageing.
