ISO 2528
Sheet Materials - Determination of Water Vapour Transmission Rate (WVTR) - Gravimetric (dish) Method
ISO 2528:2017 specifies a method for the determination of the water vapour transmission rate (often erroneously called "permeability") of sheet materials.
This method is not generally recommended for use if the transmission rate is expected to be less than 1 g/m2 per day or for materials thicker than 3 mm. In such cases the method specified in ISO 9932 is preferred.
The method cannot be applied to film materials that are damaged by hot wax or that shrink to an appreciable extent under the test conditions used.
Water Vapor Permeability Tester W301
W301 Water Vapor Permeability Tester is based on the gravimetric method and can be used to test the WVTR of sheet materials and containers.
Water Vapor Permeability Tester W306
W306 Gravimetric Method Water Vapor Permeability Tester can be used to test the WVTR of plastic films, papers, sheets, containers and other materials.
Water Vapor Permeability Tester W309
W309 Water Vapor Permeability Tester is based on the gravimetric (cup) method and can be used to test the WVTR of plastic films, sheets, and other materials.
We hope this helps and as always, we aim to ensure we can help and be proactive.
