适用范围：WARNING — Persons using this International Standard should be familiar with normal laboratorypractice. This standard does not purport to address all of the safety problems, if any, associated withits use. It is the responsibility of the user to establish appropriate safety and health practices and toensure compliance with any national regulatory conditions.CAUTION — Certain procedures specified in this International Standard may involve the use orgeneration of substances, or the generation of waste, that could constitute a local environmentalhazard. Reference should be made to appropriate documentation on safe handling and disposal afteruse.This International Standard 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 and3,0 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 throughdifferent 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.
