Analysis of full-scale fire tests of wall linings in ranch house

In the 1960's, a total of four tests were conducted in a three room arrangement in a ranch house. The tests were all initiated by ignition of a 4.4 kg wood crib, in the living room, near an easy chair, which itself ignited very soon afterwards. Measurements made included temperatures, in °F, at 24 locations throughout the structure. The concentrations of carbon monoxide, carbon dioxide and oxygen were measured. The original data interpretation was restricted to a consideration of whether flashover was or was not reached and little else. A new analysis of the data, however, permitted determination of broad approximations to heat release and comparisons with data from other standard fire test methods.
