Plastic films and sheets are described in this standard as a test method for gas permeability using the differential pressure method. The standard specifies the requirements of the test device, the preparation of the specimen, the test process and the method of calculating the data. This method is used to evaluate the performance of plastic materials in gas isolation to ensure their suitability for gas barrier requirements in Encasement and Miscellaneous applications.
