Abstract
Worldwide, wood-based materials are massively exploited in many industries. As a renewable material with significantly lower environmental impact compared with conventional materials is very likely that their production will grow in the future. This paper deals with the determination of parameters characterizing the initiation of not only solid wood as the original raw material but also of other composites produced from it. Specifically, the parameters are: critical heat flux, thermal response parameter, initiation temperature and apparent thermal inertia. These parameters are calculated based on the dependencies between external heat flux and time to initiation suggested in the literature. During the measurement, samples of selected materials were dried to zero humidity and subsequently exposed to thermal radiation of varying intensities using a cone emitter. The results of these measurements were evaluated by graphs. Calculated values of initiation parameters are listed in a summary table and can be used for further calculations in the area of personal and property fire protection.
