- Abstract
- Standard test methods ASTM F 739 , and F 1407 , are widely used to evaluate the chemical resistance of protective clothing materials. However, these techniques are not well adapted to solvents of low volatility. In this study, the chemical resistance of protective materials to solvents was investigated with volumetric and swelling techniques and compared with the standard permeation techniques. Swelling results were obtained by following the dynamic deformation of a piece of material immersed in the solvent in a specially designed cell. The volumetric technique evaluates precisely the amount of solvent that diffuses into the material over time. The polymeric membranes were neoprene, nitrile and butyl, and the solvents were acetone, cyclohexane, -butyrolactone, tetralin (1,2,3,4-tetrahydronaphthalene), nitrobenzene, N-methyl-2-pyrrolidinone and m-cresol. The advantages and limitations of these techniques for the evaluation of the breakthrough time and permeation rate will be discussed, especially with regard to their application to solvents of low volatility.
