Abstract:

Rate of heat release is a critical parameter for evaluation of the fire properties of a material. The Large Fire Research Facility at the National Institute of Standards and Technology operates three hoods capable of determining heat release rate from oxygen consumption measurements. This report describes the methodology and apparatus used to measure heat release rate. In addition, the results from several calibration tests conducted in each hood are discussed. The heat release rates determined from hood measurements range from 120% to approximately 60% of the theoretical values for the natural gas calibration fires.
