ActiveRubber,vulcanized or thermoplastic—Determination of permeability to gases—Part 1:Differential-pressure methods
硫化橡胶或热塑性橡胶 透气性的测定 第1部分：压差法
Application Summary AI generated
This standard specifies the differential-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 seals, gaskets, and hoses used in automotive, aerospace, and packaging industries where gas barrier properties are critical. The test is conducted under controlled laboratory conditions to evaluate how effectively a rubber material resists gas transmission.
