Standard Test Methods for Water Vapor Transmission of Materials Ingestion-build-239834 It has four major layers1. Scope 1. 1 These test methods cover the determination of water vapor transmission (WVT) of materials through which the passage of water vapor may be of importance, such as paper, plastic lms, other sheet materials, berboards, gypsum and plaster products, wood products, and plastics. The test methods are limited to specimens not over 1 in. [32 mm] in thickness except as provided in Section 9. Two basic methods, the Desiccant Method and the Water
