Ignition of Wood-Based Boards by Radiant Heat

Particleboards (PB) and oriented strand boards (OSB) are commonly used materials in building structures or interiors. The surface of may hence become directly exposed to fire radiant heat. aim this paper is evaluate the behaviour uncoated particleboards OSB following ignition parameters were observe process particleboard ignition: heat flux intensity (from 43 50 kW.m-2) temperature. time-to-ignition mass loss with thicknesses 12, 15 18 mm monitored compared. experiments conducted on a modified device accordance ISO 5657: 1997. Results confirmed thermal degradation samples. Heat had significant effect (burning rate) time-to-ignition. higher time than started later, i.e., at temperature that particleboards, but also particleboards. samples yielded same results above 47 kW.m?2. Thermal analysis decomposition (179 °C) compared (146 °C). difference both stages did not exceed 1%.
