Scope: This standard specifies two methods for determining the permeability of volatile liquids to rubber when they diffuse into the atmosphere by measuring the transmission rate. This method is only applicable to sheet materials and coated fabrics with a thickness between 0.2mm and 3.0mm. This method is limited to the determination of the transmission rate greater than 0.1g/m2·h. This method is especially suitable for comparing the permeation rate of the same liquid to different rubbers and the permeation rate of several liquids to the same rubber. Method A: Refilling liquid is required for testing a mixture of several liquids with different transmittances. Method B: No need to refill the liquid, used for testing single-component liquids.
