Abstract :This study carried out to determine the combustion properties of the sessile oak wood insert ignore into journalissuearticles values( Quercus petraea L.); which impregnated with wood preservative and subjected to surface treatments. For this purpose, the samples, which were prepared from sessile oak wood according to ASTM–E 160-50 combustion principles,  impregnated with wolmanit-CB insert ignore into journalissuearticles values(WC); and tanalith-E insert ignore into journalissuearticles values(T); in accordance with ASTM-D 1413-76 and then synthetic insert ignore into journalissuearticles values(St); and Water-based insert ignore into journalissuearticles values(wb); varnishes were applied according to ASTM-D 3023. The combustion test was carried out in 3 stages, combustion with flame insert ignore into journalissuearticles values(CWF);, self-combustion without flame source insert ignore into journalissuearticles values(CWOF); and ember combustion stage insert ignore into journalissuearticles values(ECP);. It was aimed to determine the combustion temperature values in CWF, CWOF and ECP stage, weight loss, total combustion time and demolition time. As a result, impregnation applications have increased the total combustion time to between 15-18% and reduced the demolition period. The exact opposite results were obtained for the varnish types, the total combustion time was reduced by 19-21% and the demolition time increased by 10-22%. In CWF stage, the highest temperature was obtained in water-based varnished samples insert ignore into journalissuearticles values(490 °C);, the lowest in non-varnished samples insert ignore into journalissuearticles values(458 °C);; in CWOF stage the highest temperature in water-based varnished samples insert ignore into journalissuearticles values(572 °C);, the lowest in synthetic varnished samples insert ignore into journalissuearticles values(544 °C);; and in ECP stage the highest temperature in non-varnished samples insert ignore into journalissuearticles values(306.5 °C);, the lowest in the samples with the synthetic varnished insert ignore into journalissuearticles values(262.7 °C);.
