Burning characteristics of materials

The feasibility of using a dynamic, i.e. multivariable, test procedure instead of the more usual single point tests has been investigated by determining the limiting conditions for burning. The rate of burning and the limiting conditions for flaming and smoldering combustion have been determined over a range of temperatures and oxygen concentrations. Results show that the relative burning rates of materials and also their relative combustion thresholds can alter significantly with changes in the tests environment.
