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.
