Parameters representing the thermal properties of materials are considered to be specific to thermal inertia, and parameters modulating surface heat transfer are considered to be related to thermal inertia. The fire behavior of materials depends on the chemical processes involved in their thermal degradation. For our study of the thermal degradation of wood, various experimental techniques have been described. They generally involve monitoring the mass and/or emission of volatile degradation products as a function of temperature. The calorimeter cone is the technique of choice for studying polymer degradation on a small scale. The cone tests enabled us to assess the fire behavior of a small quantity of our samples, and the results enabled us to compare Fraké and Tek woods both physically andthermally. From a physical point of view, our study showed that Tek wood is denser than Fraké wood. From a thermal point of view, our study showed that the two wood samples have the same fire behavior. The most striking fact is that when the radiant flux is varied, there is a small variation in the thermal values of the woods.
