water vapor transmission rate test
Gravimetric method is the arbitration method of water vapor permeability testing. Data system of sensor method should be calibrated with that of gravimetric method. 1． Water Vapor Permeability of Materials Water vapor permeability of materials is the main index in evaluating water proof property of packing materials such as film and sheets.
WATER VAPOR TRANSMISSION RATE TESTING The original standard for testing water vapor transmission of high barrier materials is referred to in the industry as "the cup method". This method involves placing a small sample of the test materials over the top of a pre-made metal cup. The cup may contain water, in which case, the water vapor would .
By studying various test methods of water vapor transmission rate, Labthink manufactures many water vapor permeability testers based on ASTM E96/GB 1037 (gravimetric method), ISO 15106-2/ASTM F1249 (infrared sensor method), ISO15106-3 (electrolytic sensor method) and ISO15106-1/ASTME398 (humidity sensor method).

In some services, such as exterior wood and masonry, the coating needs to allow the right amount of water vapor to pass through the film without damaging it. Therefore, [.] Five testing instruments plus a new test apparatus were employed to evaluate the water vapor transport properties of fabrics with low, medium, and high vapor permeability. The test results show that the desiccant inverted cup method generated the highest water vapor transmission rate, followed by the new method, the dynamic moisture permeation .
