标准摘要
[中文适用范围]： 本文件规定了通过测量传输速率来确定橡胶对挥发性液体透过性的两种方法。这些方法仅适用于厚度在0.2 mm到3.0 mm之间的片状材料或涂层面料。本标准限制于传输速率超过0.1 g/m²·h的情况。这些方法特别有用，用于比较同种材料中不同液体的相对传输速率，或者同一材料中几种液体的相对传输速率。当测试混合液体时，使用带补充的方法A；当测试单一组分液体时，使用不带补充的方法B。 [外文原描述]： 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/m 2 ·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.
