| description abstract | This method is for the gravimetric determination of the water vapor transmission rate (WVTR) of sheet materials at 37.8°C (100°F) with an atmosphere of 90% RH on one side and a desiccant on the other. It is generally suitable for any material up to 3 mm (1/8 in.) thick, although it may be used with caution for thicker materials if the edges of the specimen are completely sealed. For testing at other conditions see TAPPI T 448 "Water Vapor Transmission Rate of Paper and Paperboard at 23°C (73°F) and at 50% RH." This test can be used for both creased and uncreased specimens. See TAPPI T 465 "Static Creasing of Paper for WVT Tests" or TAPPI UM 590 "Creasing of Paperboard for Water Vapor Transmission Rate (WVTR) Testing." | |
