标准摘要
[中文适用范围]： 本标准规定了在橡胶试件各面总压力相同的条件下，用气相色谱法测定气体量的硫化橡胶或热塑性橡胶的气体透过率和透气系数的测定方法。 渗透到橡胶中。 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，并且适用于单一气体和气体混合物。 [外文原描述]： 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.
