Defining Flashover for Fire Hazard Calculations: Part II
V Babrauskas, Richard Peacock
Comparison of available correlations and predictive models used to predict the minimum energy necessary to cause flashover show consistent estimates for a range of empirical data. Still, available experimental data show a wide range of heat release rates at flashover. Additional measurement needs are suggested to facilitate better understanding of conditions prior to flashover. With analysis of both the experimental data and theoretical predictions based on available computer fire models, a significant portion of the variability can be accounted for by the time period involved in the flashover. Although typically ignored in the available correlations, qualitatively, a clear trend emerges shorter exposure times increase the needed minimum heat release rate at flashover.
