本文件规定了在橡胶试件每侧总压力相同的条件下，使用气相色谱法测定硫化橡胶或热塑性橡胶的气体传输率和气体渗透系数的方法，以确定穿过橡胶的气体量。 该方法适用于硬度不低于35 IRHD（国际橡胶硬度）的硫化橡胶和热塑性橡胶，以及单一气体和气体混合物。

This document specifies a method for the determination of the gas transmission rate and gas permeability coefficient of vulcanized or thermoplastic rubber under conditions in which the overall pressure on each side of the rubber test piece is the same, using gas chromatography to determine the quantity of gas that permeates through the rubber. The method applies 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.
