Application

This test method covers a procedure for determining the rate of water vapor transmission through flflexible barrier materials. The method is applicable to sheets and fifilms up to 3 mm (0.1 in.) in thickness, consisting of single or multilayer synthetic or natural polymers and foils, including coated materials. It provides for the determination of (1) water vapor transmission rate (WVTR), (2) the permeance of the fifilm to water vapor, and (3) for homogeneous materials, water vapor permeability coefficient.
