$a Semi-deštruktívna metóda PILODYN 6J pre meranie hustoty smrekového dreva $d Semi-destruction method PILODYN 6J for measuring wood density of spruce wood $f Alena Rohanová, Ondrej Bajza 215 $c Grafy, obr., tab. 320 $a Lit. 330 $a Density of wood has a significant impact on the assessment of construction wood quality. It is determined by various direct or indirect methods. Semi-destruction method based on PILODYN 6J device works with the dynamic stiffness. The principle is based on the penetration of steel pin into the wood by constant force (6 Joule or Nm). Moreover, penetration pin perpendicular to growth rings is required. Interaction between wood density and depth of penetration has been examined on spruce boards. Also the impact of boards side (inner, outer) has been tested. The significant statistical dependence has been identified between the depth of pin penetration on the inner and outer side and the density of wood. More significant result has been identified on the inner side of boards. The knowledge allows increasing the reliable identification of wood density by PILODYN 6J device in situ based on the consideration of the board side. 463 -1
