This standard test method is used to evaluate the performance of flexible barrier membranes and laminates under slow permeation conditions. Anti-permeability is essential for thin flexible materials to effectively prevent the infiltration of gases, odors and harmful substances, thereby protecting the mass of the product and prolonging the shelf life. This method measures the resistance to penetration of the material, including force value, energy and perforation elongation, by applying biaxial stress at room temperature until the material appears to be perforated. The probe and Test speed used in the test process may affect the results, so it is recommended to follow the test conditions in the standard when comparing different materials. This standard aims to provide a consistent test method for accurate performance evaluation of different materials.
