Apstrakt

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.
