ActiveRubber, vulcanized or thermoplastic—Determination of permeability to gases—Part 2: Equal-pressure methods
硫化橡胶或热塑性橡胶 透气性的测定 第2部分：等压法
Application Summary AI generated
This standard specifies the equal-pressure method for measuring the gas permeability of vulcanized or thermoplastic rubber. It is applied in quality control and material selection for products such as tire inner liners, seals, and hoses, where consistent gas barrier performance is critical to prevent pressure loss or contamination. The method is particularly relevant in the automotive, aerospace, and industrial sealing industries for evaluating rubber materials under controlled conditions.
