PHYSICAL TESTING OF RUBBER - METHOD FOR DETERMINATION OF THE TRANSMISSION RATE OF VOLATILE LIQUIDS
出版：British Standards Institution
專家解讀視頻
Describes two methods of determining permeability of vulcanized rubber to volatile liquids diffusing into open air, by measurement of transmission rate. Applies only to materials in sheet form, and to coated fabrics, having thicknesses of between 0.2 mm and 3.0 mm. Methods are especially useful for comparing relative transmission rates of one liquid through different materials, or of several liquids through one material. Method A, with refilling, is for testing mixtures of liquids of different transmission rates. Method B, with no refilling, is for a single-component liquid.
