This standard specifies a method for measuring the gas permeability rate and gas permeability coefficient of vulcanized or thermoplastic rubber under conditions where the total pressure on each side of the rubber test piece is the same using gas chromatography, which measures the amount of gas penetrating the rubber. The method applies to vulcanized and thermoplastic rubbers with a hardness of 35 IRHD (International Rubber Hardness Class) or higher and to single gases and gas mixtures.
