E 300   Diffusion and vapour transmission

App.D E
301   The test aims to determine the permeability of water vapour through permeable or semi-permeable materials.

App.D E
302   The water vapour permeability (WVP) is calculated as:

raster

where - DW - is the weight change, - t - is time and - A - the test area.

App.D E
303   The recommended test method is SS 02 15 82. Other tests are available: ASTM E 96-94, ISO 1663:1981, ISO/DIS 1663.
