This standard specifies two methods for measuring the gas permeability of vulcanized or thermoplastic rubber at differential partial pressures. The two methods it specifies are:
——Pressure sensor method: gas permeability rate, gas permeability coefficient, gas diffusion coefficient, Determine the gas solubility coefficient. - Gas chromatographic method: Determine the gas permeability and gas permeability coefficient. Both methods are applicable to vulcanized and thermoplastic rubbers with a hardness of 35 IRHD (International Rubber Hardness Class) or higher and to single gases and gas mixtures. do.?
