The purpose of this study was to measure fire parameters for a selected group of materials.These parameters are to be used in a continuing study of flame spread. The parameters measured are rate of heat release, rate of mass loss, heat of gasification, effective heat of combustion, stoichiometric ratio and time to ignite. Heat release rates and mass loss rates are given as a function of time for several external heat flux levels. The rate of heat release is also given as a fxinction of the total beat released. The experimental results and analysis are shown for six diverse materials representative of aircraft (interior panels, carpeting, and seat cushions) and buildings (particle board, polymethyl methacrylate (PMMA) and rigid foam).
