BS 2782英文簡介

BS 2782-5-Method 552A1999 ISO 4582-1998

ISO 2782-1:2016 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:

- pressure sensor method (using vacuum): for determining the gas transmission rate, gas permeability coefficient, gas diffusion coefficient and gas solubility coefficient;

- simplified sensor method (using applied pressure): for determining the gas permeability coefficient only;

- gas-chromatographic method: for determining the gas transmi
