ASTM E96-22: Standard Test Methods for Gravimetric Determination of Water Vapor Transmission Rate of Materials addresses two testing procedures for determining the water vapor transmission rate (WVTR) of numerous materials, both of which can be incredibly useful for knowing the potential risks posed on the materials in different humidity levels. Definition of WVT – Water Vapor Transport. WVT is the water vapor quality passing through the unit area of the sample vertically within the specified time at the speed of g/m²
Permeance is simply permeability divided by the material thickness in the direction of vapor flow; thus, permeability is a material property, whereas permeance depends on thickness. Permeability is measured with wet-cup, dry-cup, or modified cup tests. Specific test methods for measuring water vapor permeability are given in ASTM Standard E96.across or through a material, the greater the tendency for water vapor to migrate from the high pressure side to the low pressure side. EFFECT OF MATERIAL THICKNESS The perm ratings given are for stated thicknesses of materials. Generally, doubling material thickness halves water vapor transmission: if 1 inch of a material has a perm rating of .
the time rate of water vapor transmission through unit area of flat material or construction induced by unit vapor pressure difference between two specific surfaces, under specified temperature and humidity conditions • Water Vapor Permeability: the time rate of water vapor transmission through unit area of flat material of The conditions specify the mass of water vapor that passes through a unit area of the specimen in a given time. This happens under a certain difference in water vapor pressure. The unit of measure for this mass is grams per square meter Pascal hour (g/(m²-Pa-h)). 03 water permeability coefficient. The specimen is on both sides. It is to keep .
