- Abstract
- A numerical scheme is presented to correct heat release rate measurments made with the Ohio State University rate of heat release apparatus for the effects of inherent time delays in the measurement system. The magnitude of the correction is shown to increase with increasing rate of change in heat release rate. Illustrative heat release rate curves for particle board and balsa wood show that corrections to the peak heat release rate of 40% and 130% respectively are necessary. Measurements of the apparatus time response to step changes in heat release rate are reported. A simple method of determining corrections to the measured peak heat release rate is discussed.
