- Abstract
- The combustibility properties of polyethylene, polyvinylchloride and silicone rubber have been evaluated. The autogenous ignition temperatures of these materials have been determined as a function of atmospheric composition and pressure under standardized conditions in Dynamic Science Corporation's Combustion Monitor Model 164. The degradation and oxidation products from these materials were identified by gas chromatographic analysis. In addition, the burning rate of these materials was determined under test conditions simulating the environment found in missile silos and high performance aircraft. Two candidate agents have been synthesized for evaluation as first-aid fire extinguishing agents on Class B fires (liquid). The combustion properties of selected flammable materials in enriched oxygen environments and zero gravity flight conditions will be evaluated. A survey has been made to select fire extinguishing agents for use in an orbiting manned spacecraft. Four candidate agents have been selected for evaluation under enriched oxygen atmospheres. The effectiveness of these agents will be evaluated during the coming year. Methods of application of these agents under zero gravity flight conditions will be evaluated.
