Abstract
In practical applications a given material can be exposed to a wide range of scenarios and its flammability can change depending of the ambient conditions. Therefore a material that is expected to be fire resistant can present a completely different behavior under different conditions. In this work, experiments were conducted to study the effect of oxygen concentration, ambient pressure and external radiant heat on opposed flow flame spread rate over a thin, fire resistant, Nomex-based fabric sample in a mixed buoyant/forced flow. Flame spread rates were measured over a range of ambient pressures (40 100 kPa) with oxygen concentrations varying from 25% to 33%. Infrared heaters supplied a decaying radiant flux, ranging from 5.4 kW/m2 at point of ignition to 0.7 kW/m2 at the opposite end. Observed trends in flame spread are compared to theoretical predictions.
