Method for classification of round timber with wood moisture measuring device for masts, particularly for line construction, involves introducing pin, particularly metal pin with predetermined penetration depth into round timber

摘要

The method involves introducing a pin, particularly a metal pin with a predetermined penetration depth into the round timber (1), where the force required for penetration into the round timber is measured. The round timbers are classified as a function of the measured force for use as a mast. The penetration depth is specified as a function of the core sapwood boundary of the round timber and is about 10 to 20% of the diameter of the round timber added to the height of the force measurement. The compressive force in the longitudinal direction of the round timber is detected at two points.
