Abstract

This document lists visual strength grades, species and sources of timber, and specifies the strength classes to which they are assigned. The assignments listed are for strength classes documented in EN 338. The assignments apply to timber that has not been previously strength graded in a way that introduces a bias on the population of timber to be graded, as compared to ungraded material. Species/grades or species combination/grades are assigned to strength classes in accordance with EN 14081-1 and supporting standards. This document contains a list of assignments but is not intended to be exhaustive. NOTE 1 Timber graded by machine to EN 14081 is graded directly to the strength classes and marked accordingly. Machine grading is therefore not referenced in this document. NOTE 2 For combinations of species and visual grades which meet the requirements of EN 14081 but are not listed in this document, the assignment to strength classes is made according to EN 384.
