Lëndë drusore e strukturuar - Përcaktimi i vlerave karakteristike të vetive mekanike dhe të masës vëllimore

Structural timber - Determination of characteristic values of mechanical properties and density

Scope

This European Standard gives a method for determining characteristic values of mechanical properties and density, for defined populations of visual and/or mechanical strength grades of sawn timber.
A method is also given for checking the strength of a timber sample against its designated value.
The values determined in accordance with this standard for mechanical properties and density are suitable for assigning grades and species to the strength classes of EN 338.
NOTE 1 For assigning grades and species to the strength classes in EN 338 only three characteristic values, i.e. bending strength, mean modulus of elasticity parallel to grain and density, need to be determined, other properties may be taken from the table in EN 338.
NOTE 2 EN 1912 gives examples of assignment to strength classes of established national or regional visual grades.
