One approach to predict physical or chemical processes promorting flashover is shown. This is based on the characterization of flashover as a thermally unstable phase in transient compartment fires (studied in the 2nd report, Transactions of AIJ, #311, 1982). The processes promoting flashover are defined as those which can lead to the appearance of thermal instability. The discriminants and some practical indices to investigate these processes are derived. A few typical examples of the functions promoting thermal instability and the processes corresponding to these are also studied.
