Vertical, horizontal and 45° upward flame spread experiments over the small scale beech and pine wood samples were performed. Wood samples were of two geometries - square cross section prisms (15 x 15 mm) and a thin rectangular cross section prisms (5 x 40 mm) - and of three different lengths - 10, 15 and 30 cm. Samples were ignited by a heptane source fire extinguished immediately when the wood samples ignited. During the flame spread an internal temperature profiles along the centreline of

Flame spread was observed in all sample positions except the horizontal orientation of the beech and pine square prism samples. Experimental data will serve for a validation of the pyrolysis models in the Computational Fluid Dynamics (CFD) flame spread models.
