✦ Synopsis


This paper presents the progress of an experimental study to develop a laboratory-scale test to define the burning intensity of various commercial samples of plastics. In the study, a steady state heat balance at the burning surface has been used to derive the burning intensities. An 'ideal' burning rate has been defined, which appears to correlate with full-scale fire test data. Conditions for the burning intensities in full-scale fires are postulated• Data for heat of gasification]pyrolysis/depolymerization, heat flux transferred from the flame to the surface, heat flux lost by the surface, and minimum mole fraction of oxygen required for flame extinction are presented for 16 commercial samples of plastics, a wood, and a plywood sample and six organic liquid samples

Fuel-lean flammability limits and burning velocities in a closed vessel were measured for methane-air mixtures burning at earth gravity (one-g) and zero-gravity (zero-g) at initial pressures of 50-1500 Tore The zero-g flammability limit was found to be between the one-g upward and one-g downward fla
