GB/T 7755.1-2018 Rubber,vulcanized or thermoplastic—Determination of permeability to gases—Part 1:Differential-pressure methods
Abstract
This part of GB/T 7755 specifies the test methods for determining the air permeability of vulcanized rubber or thermoplastic rubber using the pressure difference method, including the determination of gas permeability, gas permeation coefficient, gas diffusion coefficient, and gas dissolution coefficient. This part is applicable to vulcanized rubber or thermoplastic rubber with a hardness of not less than 35 IRHD (International Rubber Hardness), and the test gas can be a single gas or a mixed gas.
