DIN EN 1912:2010-07

This European Standard lists visual strength grades, species and sources of timber, and specifies the strength classes from EN 338, to which they are assigned. For the grades, timber species and sources indicated, there is long experience of use and/or satisfactory test data. The sources listed are therefore largely determined by existing commercial practice. This document contains Amendment A1, which has been approved by CEN on 2006-12-28, Amendment A2, which has been approved by CEN on 2008-02-02, Amendment A3, which has been approved on 2009-04-21, and Amendment A4, which has been approved by CEN on 2010-02-11. This European Standard has been prepared by Technical Committee CEN/TC 124 "Timber structures", the secretariat of which is held by SFS (Finland).
