    Abstract

    Test methods are described for measuring the flammability of materials used in chemical protective clothing. Vertical and 45° type flame test procedures have been used to evaluate and classify the flammability of selected materials supplied by the U.S. Coast Guard. Test protocols have been developed to measure the resistance to hot surface contact and to low heat similar to the maximum temperatures expected under severe storage conditions. This research used these test methods to evaluate a selected group of chemical protective suit materials. This program also evaluated the effect of a chemical protective suit layer on the thermal protective performance of Nomex fabric and firefighter's turnout coat ensemble. Analytical methods are used to assess the effects of convective heat exposure on the thermophysical properties of chemical protective suit materials and to explain the effects of heat on the chemical permeation resistance of these materials.
