The use of heat-treated woodmaterial and eco-friendly impregnation chemicals are steadily increasing in thewoodworking industry over the last decades. In this study, the effects of applicationsof impregnation and heat treatment on combustion properties of Hornbeam (Carpinus betulus L.) wood wereinvestigated. The test specimens were impregnated with Imersol-aqua (Ia) andTimbercare-aqua (Ta) impregnation material according to ASTM D 1413-76standards. Impregnated specimens were subjected to heat treatment at 150, 170and 190 °C for 2 h. The temperature of flame source combustion, the temperatureof without flame source combustion and varying light intensities (Lux)depending on the smoke production in these combustion stages were determinedaccording to ASTM E 160-50. According to the test results, the highestcombustion temperature of flame source combustion was determined inunimpregnated and heat-treated samples at 190 °C, while the highest combustiontemperature of without flame source combustion was determined in impregnatedwith Ta and heat-treated samples at 170 °C. The highest light density in flamesource combustion phase was determined in unimpregnated and heat-treated samplesat 190°C, while in without flame source combustion was in unimpregnated andheat-treated samples at 170°C. As a result, as the heat treatment temperatureincrease, the combustion temperature increased and the smoke density decreased.In addition to impregnation materials increased the smoke density while reducedthe combustion temperatures of test specimens.
