Abstract: This study provides up-to-date, representative values of the physical and mechanical properties of silver fi r wood from the Spanish Pyrenees for comparison with other provenances and timber species. Tests were conducted with clear specimens obtained throughout the tree stem and properties were determined following the UNE standards of the corresponding tests. The wood was found to be light (ρ= 0.48 g/cm3), soft (H=1.71 mm-1) and moderately stable (v=39.43%). Its bending strength (MOR=78.70 N/mm2) is low and its compressive strength (MCS=44.88 N/mm2) is average. Impact behaviour is average (K=41.46 N/mm) and cleavage behaviour (C=19.92 N/mm) is low, as are tangential and radial tension perpendicular to the grain (1.71 and 1.68 N/mm2). The differences obtained in comparison with other provenances of this species may be the result of the location of the silver fi rs at the edge of their geographical distribution and thus the specifi c conditions of the site have a greater effect on the wood properties.
