ISO 6179:2017规定了两种方法，通过测量透射率来确定橡胶对扩散到露天的挥发性液体的渗透性。 它仅适用于片材形式的材料和厚度在0.2 mm和3.0 mm之间的涂层织物。 它被限制在大于0.1 g/m2·h的传输速率。 这些方法对于比较一种液体通过不同材料的相对传输速率或几种液体通过一种材料的相对传输速率特别有用。 当测试具有不同传输速率的液体混合物时，使用重新填充的方法A。 方法B，无需再填充，用于单组分液体。 注:ISO 2528中给出了水蒸气透过率的测定方法。

ISO 6179:2017 specifies two methods for determining, by measurement of the transmission rate, the permeability of rubber to volatile liquids diffusing into open air. It is applicable only to materials in sheet form and to coated fabrics having thicknesses between 0,2 mm and 3,0 mm. It is restricted to transmission rates of more than 0,1 g/m²·h. The methods are particularly useful for comparing the relative transmission rates of one liquid through different materials, or of several liquids through one material. Method A, with refilling, is used when testing mixtures of liquids which give different transmission rates. Method B, with no refilling, is used for a single-component liquid. NOTE A method for the determination of water vapour transmission rate is given in ISO 2528.
