- Abstract
The paper attempts to compare the classification of sawn timber based on the norms used in Poland (PN—75/D—96000) and those valid in the European Union (PN—EN 1611—1). For the research, long pine logs were taken from five research areas in Poland. The obtained sawn materials were divided according to their origin into lengths of the logs. It was shown that regardless of the origin of the stand, knots are the dominant defect, while the role of other wood defects is much lower. Direct comparison of the classification according to Polish and European standards is very difficult due to the differences in the acceptable range of individual wood defects. The raw material classified by the Polish standard shows a higher proportion of sawn timber of higher classes than the one classified by the European standard, so the Polish standard is less rigorous than the European one.
