BS EN ISO 12572:2016 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. Annexes give details of test methods suitable for different material types.The results obtained by this method are suitable for design purposes, production control and for inclusion in product specifications.Cross References:ISO 9346ISO 12570ISO 12571ISO 15148BS 5250:2011ASTM E96-80All current amendments available at time of purchase are included with the purchase of this document.
