Project Details
Description
The primary objective of this project is to establish the experimental basis for the assignment of Danish grown Sitka spruce to the European strength class system.
Sufficient quantities of representative samples of Sitka spruce specimens are investigated in order to establish the characteristic strength values necessary for entering into the European strength class system (EN 338). All the material tested is subjected to visual grading according to INSTA 142 and the ECE rules. In addition, three different grading machines are included.
In addition to the establishment of strength and stiffnes values the relations between the non-destructive parameters and the mechanical properties are studied. The variance between sawmills is quantified.
The results have formed the basis for the inclusion (1999) of Danish sitka spruce in EN 1912.
