Automatic ASTM D1653 Water Vapour Transmission tester
Labthink W3/060 Water Vapour Transmission Tester evaluates the water vapor transfer through semi-permeable and permeable samples. The data can be used by manufacturers and designers and is often important in packaging applications.
A cup is filled with distilled water leaving a small gap of air space between the specimen and the water. The cup is then sealed to prevent vapor loss except through the test sample. An initial weight is taken of the apparatus and then periodically weighed over time until results become linear. Caution must be used to assure that all weight loss is due to water vapor transmission through the specimen.
W3/060 Water Vapour Transmission Tester conforms to the following standards:
ISO 2528, GB 1037, GB/T 16928, ASTM E96, ASTM D1653, TAPPI T464, DIN 53122-1, JIS Z0208, YBB 00092003
