Full Description



This method is intended for use in determining the resistance of textile materials to water vapour diffusion.

Three options (Information which may be useful in the selection of option can be found in Appendix A.) are available for testing, allowing for the resistance to water vapour diffusion of a textile material to be determined at one, or more, of three positions within the air gap of the test apparatus.

The testing and evaluation of a product against this method may require the use of materials and/or equipment that could be hazardous. This document does not purport to address all the safety aspects associated with its use. Anyone using this method has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any applicable regulatory requirements prior to its use.
