This study carried out to determine the combustion properties of the
sessile oak wood (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 (WC) and
tanalith-E (T) in accordance with ASTM-D 1413-76 and then synthetic (St) and
Water-based (wb) varnishes were applied according to ASTM-D 3023. The
combustion test was carried out in 3 stages, combustion with flame (CWF),
self-combustion without flame source (CWOF) and ember combustion stage (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
(490 °C), the lowest in non-varnished samples (458 °C); in CWOF stage the
highest temperature in water-based varnished samples (572 °C), the lowest in
synthetic varnished samples (544 °C); and in ECP stage the highest temperature
in non-varnished samples (306.5 °C), the lowest in the samples with the
synthetic varnished (262.7 °C).
