DEVELOPMENT OF FIRE RESISTANCE RATINGS FOR SHELTER COMPONENTS

Abstract

Experiments were performed to evaluate the responses of shelter components to typical fire exposures in order to develop means for predicting these responses from the results of a minimum number of standardized tests. Exposures were provided by an infrared lampbank. Samples included material of both high and low insulating qualities, inert materials, and those exhibiting ablative and dehydration processes. Each sample was approximately 16-in. wide, 24-in. high and 2-in. thick. Results indicate that fire resistance of a barrier is considerably affected by the intensity of exposure. For homogeneous combustible materials, this effect can be expressed approximately in terms of the area equivalence method suggested by Ingberg. For homogeneous non- combustible materials, containing free water, this method produced errors ranging from 10 to 31 percent. This error is substantially larger for materials containing both free and chemically-combined water. In the case of non- homogeneous materials, the error ranged from 62 to 86 percent.
