Abstract

In the submitted paper, the fire risk of the oriented strand boards (OSB) and chipboards is assessed. Fire risk of these materials was assessed on the basis of heat flux density effect on the ignition time of tested materials with thickness of 12, 15 and 18 mm. The dependence of initiation time on the heat flux density was determined by the apparatus (cone heater) according to the ISO 5657:1997 through the modified testing procedure. The testing procedure modification consists of specimen heat flux exposure without any secondary initiator use. The minimal heat flux density at which ignition occurred was 43 kW / m2 for the OSB boards, and 40 kW / m2 for the chipboards. The obtained data show that the ignition time of assessed wooden materials decreases exponentially with increasing heat flux density. Obtained data imply also a fact that the influence of studied materials thickness on the ignition time decreases with increasing heat flux density. Measured data imply an independence of minimal heat flux density on studied materials thickness, as well.
