Abstract:

From the 1980's to the early 1990's, numbers of studies were conducted on the prediction of the occurrence of flashover by one-dimensional analytical/numerical flame spread models. It is believed that these studies have helped development of rational evaluation method of the fire safety of lining materials. However, although many of the studies along this approach have derived simple models, diagrams or formulae, they have been seldom validated by practitioners nor succeeded by studies on larger compartments while most of these studies dealt with the ISO9705 Room Corner Test. Also, it is believed that models and conclusions of these studies have inevitable limitations due to its simplicity and rich variety of the combustion behavior of practical lining materials. It also seems that there are several overlooks in this approach, especially in the interpretation of the theoretical concepts and the phenomena that actually happen in the fires. This approach is being revisited for the subjugation of the gap between the theory and real/practical world.
