Abstract
The report contains the results of the resistance of contaminated protective membranes to harmful chemical. The protective materials used were; nitrile rubber, bromo butyl rubber and natural rubber. Toluene and octane were used as contaminants. They form the main components of gasoline available in the market. The penetrants used were; acetone, chloroform, propyl ether, dicholormethane pentane. The permeation tests were carried out at temperatures of 20, 30, 40 and 50C. For some penetrants, no permeation tests were performed at the higher temperatures since the boiling point of pentane and of dichloromethane is less than 50C. Most of the tests were performed using the ASTM method F-739-85 in conjunction with a GC apparatus for detecting the chemicals. The same analytical technique was used for quantitative analysis. A protocol was developed in order to study the resistance of contaminated protective polymeric materials to harmful liquid chemicals using the ASTM method.
