The aim of this study was to investigate the effect of heat treatment intensity, moisture content and testing temperature on the transverse fracture properties of thermally modified Norway spruce in the radial-tangential TR and tangential-radial (TR) crack propagation systems. Small compact tension (CT) specimens were subjected to pure mode I loading, and load-CMOD curves were recorded. Characteristic fracture parameters were calculated. Thermal modification altered both the calculated fracture parameter values and the changes increased as the severity of heat treatment increased. The parameters were altered more in the RT than in TR crack propagation system.
