Hygrothermal performance of building materials and products. Determination of water vapour transmission properties. Cup method Ingestion-build-86103 BS IEC 62899 discusses printed1 Scope This document specifies a method based on cup tests for determining the water vapour permeance of building products and the water vapour permeability of building materials under isothermal conditions. Different sets of test conditions are specified. The general principles are applicable to all hygroscopic and non hygroscopic building materials and products, including insulation materials and including those with facings and integral skins.
