Descripción
Three samples of sawn Radiata pine (Pinus radiata D. Don) timber, consisting of 150 pieces with dimensions of 80mmx120mmx2400mm, 80 pieces with dimensions of 150mmx200mmx4500mm, and 75 pieces with dimensions of 150mmx250mmx5600mm, were visually graded according to the Spanish standard UNE 56544 (2011) to analyze the influence or visual grading requirements on both the grading yield and mechanical properties. The resulting percentages of the rejected pieces stood at 19 and 28% for 150x250mm crooss-section pieces, respectively. That percentage increased to 73% for 80x120mm cross-section pieces. The grading yield and mechanical properties were then analyzed to determine the influence of warp defects. Three different criteria for limitng warp defects were considered, bending strength, and density were obtained. The results concluded that loosening specified requisites improves the visual grading output in the smallest cross-section, with no significant reduction in the mechanical properties. A proposal for a less rigorous specification of twist defects in the Spanish visual grading standard has been introduced.
