BS EN 1931 is a series on flexible sheets for waterproofing. Flexible sheets for waterproofing are used to prevent water from contacting another material that it is placed over. BS EN 1931 specifies a method for the determination of the water vapour transmission properties and the calculation of the density of moisture flow rate g and the moisture resistance factor u of
