    Abstract

    Air permeable chemical protective clothing materials provide protection against permeation of toxic liquids and gases, while also allowing the permeation of air and moisture vapor. Evaluating the chemical permeation resistance of air permeable materials presents a technical challenge. Therefore, a novel apparatus was developed, which was specially designed to evaluate the penetration of chemical vapors through this type of air permeable protective clothing materials. The test apparatus was developed by modification made to a device used to conduct the ASTM F739 test. The details of the apparatus are described. The advantages of the experimental approach are also discussed.
