Abstract

Natural wood is one of the main sources of interior finishing of buildings, such as offices, kitchens, and furnishings that are widely used in Jordan. Inevitable hazards of wood fires have encouraged scientists and researchers for further investigations and tests in order to improve fire-resistance and to provide efficient protection from fire. Wood types of Beech, Oak, Pine, and Hickory were selected and tested since they represent the 40% of the total natural wood used in Jordan. Dual calorimeter approach under ISO 5660-1:2002, as a fire-testing device, is utilized to measure, experimentally, the thermal properties of wood samples during flaming combustion. The tested samples have been exposed horizontally in order to incident heat fluxes of 50 kW/m2. Time to ignition, heat release rate, burning rate or mass loss rate, effective heat of combustion, total heat release and concentration of carbon monoxide production have been measured. Moreover, the effect of paint has also been investigated as a fire retardant for the safety of furniture. The results show that treating wood with fire retardant materials affects the flaming behavior and significantly reduces the heat release rate and other ignition parameters during a period of 360 seconds. The average value of heat release rate for Beech types is 142.71 kW/m2. The reduction in heat release rate reaches a value of 18.43% for Pine wood types.
