The Effects of Outdoor Conditions on the Combustion Properties of Scotch Pine (Pinus Sylvestris L.) Wood

Abstract

The wooden material, which is a light and durable material, has also undesirable properties such as contagion from outdoor conditions and combustion properties. This research is conducted with the intent of determining the combustion properties of wood material left in outdoor conditions for one year. For this purpose, samples prepared from scotch pine (Pinus sylvestris L.) according to ASTM-E 160-50 are first impregnated with tanalith-E (T) and wolmanit-CB (W-CB) in compliance with ASTM-D 1413-76, and then are varnished with synthetic (St) and water based (wb) varnish according to ASTM-D 3023. The weight loss, the collapse time in combustion, the total combustion duration, the temperature values in the combustion levels are identified by subjecting pieces, which are left in outdoor air conditions, to combustion tests according to the principles specified in ASTM G7-05 standard by the end of the year. According to the results, the impregnation materials have decreased the collapse time by %7-26 in the combustion, increased the total combustion duration by %14-34, and the varnishes have raised the collapse times and reduced the total combustion durations
