DIN EN ISO 6179:2010-08

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. The methods are applicable only to materials in sheet form or to coated fabrics having between 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 liquid 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 homogeneous single-component liquids. The Committee responsible for this standard is NA 054-04-04 AA "Kunststoff-Folien und kunststoffbeschichtete Flächengebilde (Kunstleder); allgemeine Eigenschaften" ("Plastic films and plastics-coated fabrics (artificial leather); general characteristics") at DIN.
