摘要：

For the determination of properties of block boards, ASTM D-5751 standards are applied. When board thickness does not achieve that specified by ASTM, test specimens with a lower shear surface must be prepared. In order to determinate the effect of shear surface on shear. strength and adhesion, test specimens with three different shear surfaces, one of them the specified by ASTM, were tested. Boards were made up with Pinus radiata and jointed with polyvinyl acetate (PVA). Results showed that when no artificial aging was applied, no significant differences were founded. After treatments under boiling water or vacuum and pressure statistically significant differences were denoted.
