Abstract (2. Language): 
In this study, it was evaluated important performance characteristics of wood and wood based products, which are ignitability, heat release rate, flame spread index, smoke and toxic gases and, charring rate. Thermal degredations of cellulose, hemicellulose and, lignin which are individual components of wood were investigated. Moreover, it was evaluated effect of fire retardant chemicals on this performance characteristics and determined effects on wood and wood based products in service.
Abstract (Original Language): 
Bu çalışmada odun ve odun esaslı ürünlerin yangında performanslarının belirlenmesinde önemli karakteristikleri olan tutuşabilirliği, ısı yayılma oranı, alev yayılma indeksi, duman ve zehirli gaz oluşumu, kömürleşme oranı irdelenmiş ve odunun ana bileşenleri olan selüloz, hemiselüloz ve ligninin termal degredasyonu ele alınmıştır. Ayrıca, yanmayı geciktirici kimyasalların bu performans karakteristikleri üzerine olan etkisi incelenerek kullanım yerinde odun ve odun esaslı ürünler üzerindeki etkileri ortaya konmuştur.
