The ASTM D1434-23 standard provides a test method for determining the gas permeability of Plastic films and sheets. This method is used to evaluate the rate of gas transport through plastic materials and covers the estimation of steady-state gas transport rates for films, sheets, and plastic-coated paper or fabrics. Test results are useful for understanding the gas permeability performance of materials, although relevance to practical applications needs to be empirically determined on a case-by-case basis. The method includes two procedures: a pressure measurement procedure (M) and a volume procedure (V) for the measurement of gas transport in different ways. The accuracy of test results may vary due to inter-laboratory differences and material influences, and it is recommended to consider these factors when using them. This standard does not address sealing testing in Encasement applications, nor does it apply to refereeing purposes, unless the buyer and seller test at a mutually agreed level of accuracy.
