The standard GB/T 1037-2021 Plastic film and sheet water vapor transmission performance determination, cup weight gain and weight loss method specifies two cup measurement methods (weight gain method and weight loss method) for evaluating the water vapor transmission performance of Plastic film and sheet. This standard applies to the water vapor transmission performance test of Plastic film and sheet, and can also be used for the test of paper, non-woven fabrics and artificial leather. The standard describes the definition of water vapor transmission amount and water vapor transmission coefficient in detail to ensure the accuracy and conformity of the test results. The standard refers to the relevant national standards for plastic sample conditioning, Film thickness determination and analysis of water use to support the specification and precise operation in the test process.
