Scope: This standard specifies the terms and definitions, symbols and units, principles, instruments, equipment and materials, test pieces, test procedures, calculation and expression of results, and accuracy of measurement methods for water vapor transmission performance test methods of building materials and their products. and test reports. This standard applies to hygroscopic and non-hygroscopic building materials and their products, including materials and products with natural skin or finishes. This standard specifies different test methods for different materials and their products. This standard is not applicable to the determination of building materials and their products whose water vapor equivalent air layer thickness is less than 0.lm.
