Differences in Values of Volume of Unedged Sawn Boards as a Result of Different Width Measurement Methods

The paper discusses various methods of measuring the width of unedged sawn boards with nominal thickness of 50, 60 and 80 mm, as well as the importance of measuring methods for the calculation of their volume. The starting point in determining the method of measuring the width of the boards were Cro...

The starting point in determining the method of measuring the width of the boards were Croatian and European regulations as well as common methods of measuring used in Croatian sawmills.

For 50 mm thick sawn boards, the highest values of the measured volume were obtained by applying a measurement method common in Croatian sawmills, labelled as P2.

The EN method of measuring the width of sawn boards of 60 and 80 mm thickness resulted in the highest value of volume, followed by the HRN2 method, and finally methods used in the sawmills labelled as P2, P1 and HRN1; however differences were statistically signifi cant only with 80 mm sawn boards.
