ON THE ROLE OF KPC OF ROOM LINING MATERIALS ON THE GROWTH OF ROOM FIRES

The role of the product of the thermal properties of thermal conductivity and thermal capacity per unit volume in fire growth is explored in relation to a simple model of a room fire. The calculated differences between flashover times for two different lining materials are plausible; the main conclusion is to show that the flashover time depends on KρC in a weaker relationship than simple proportionality.
