GB/T 30801-2014 Hygrothermal performance of building materials and products—Determination of water-vapour transmission properties—Box method
Abstract
This standard specifies the test method for determining the water vapor permeability of building materials by the box method. The box method is mainly suitable for low water vapor permeability materials, whose surface water vapor permeability resistance cannot be ignored.
