Wood and wood boards that are part of the structure and/or furniture of buildings, in case of fire, contribute to the spread of fire. The objective of the research was to determine the ignition time and mass loss based on indicative fire reaction tests on Pinuspseudostrobus specimens, slatted boards, plywood, medium density fiberboard and oriented strand boards. 35 small specimens of each material were prepared and their moisture content and density were calculated. Fire reaction tests were carried out and the ignition time and mass loss were determined. Density increases in the following order: slatted boards, plywood, P. pseudostrobus, medium density fiberboard, and oriented strand board. It was concluded that comparatively, the ignition time of the slatted and medium density are similar and the shortest; the time corresponding to plywood is close to that of P. pseudostrobus wood; and the ignition time of oriented chip board is the longest. The mass loss of P. pseudostrobus wood is lower compared to that of plywood and oriented chip boards. The mass loss of medium density fiberboard and slatted boards is higher and similar to each other. For the four wooden boards studied, as their ignition time increases, their mass loss decreases.
