On the use of visual and machine sorting of sawn timber
The article provides a comparative assessment of the possibilities of visual and machine sorting of sawn timber. It is noted that in conditions of depletion of forest resources, visual sorting of sawn timber according to the criteria of GOST 8486 cannot guarantee strength indicators corresponding to the assigned type of wood. while machine sorting allows for an objective sorting of wood according to the normalized values of strength, modulus of elasticity and density, according to the specified lower limits of their standard values. Using the example of the second grade wood (strength class C24), the influence of the statistical scatter of data on the rejection minimum assigned during machine sorting of sawn timber is considered.
