AB The paper presents the resisitance of wood against a pilot flame. The fire has negative effect on the wood and its properties. The fire and its high temperature cause a degradation of chemical components of wood. Hence the physical properties are changed and strength of the wood is decreased. The combustion velocity and the loss weight depend on the material's thickness. For tests have been chosen groups of samples with thickness of 5, 10, 15 and 20 mm.The result of submitted work is a time estimation of the fire penetration and an observation of weight losses coupled with visual changes observation of degraded samples. It have been established that with an action of the pilot flame the needed time to fire penetration is rising with rising material's thickness and at the same time the cumbustion velocity is decreasing.
