About This Item
Full Description
This document specifies three methods for the determination of the permeability to gases of vulcanized or thermoplastic rubber under a differential partial pressure.
The three methods specified are as follows: — a pressure sensor method (using vacuum): for determining the gas transmission rate, gas permeability coefficient, gas diffusion coefficient and gas solubility coefficient;—; a simplified sensor method (using applied pressure): for determining the gas permeability coefficient only;
— a gas-chromatographic method: for determining the gas transmission rate and gas permeability coefficient. These methods apply to vulcanized and thermoplastic rubbers of hardness not less than 35°IRHD (international rubber hardness degrees) and to both single gases and mixtures of gases.
