Rubber, vulcanized or thermoplastic. Determination of permeability to gases - Differential-pressure methods
BS ISO 2782-1:2022 发布历史
1 Scope 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.
