摘要：

In the presented paper is comprehensively assessed the behavior of spruce and birch wood during fire. Samples were loaded by heat flux of 20, 35 and 50 kW/m(2) in apparatus according to ISO 5657. The duration of the test was up to 30 min. The behavior of the samples was evaluated on the basis of charring rate and concentrations of carbon monoxide in smoke. Charring rate was rising with increasing heat flux density and decreasing linearly with increasing density of the samples. The maximum concentration of CO in the smoke for spruce and birch wood was observed just before the end of the test, during the phase of char layer burning.
