Structural timber. Strength classes. | Status: Revised, Superseded, Withdrawn

1 Scope This European Standard establishes a system of strength classes for general use in structural codes. It gives characteristic strength and stiffness properties and density values for each class and the rules for the allocation of timber populations (i.e. combinations of species, source and grade) to the classes. This standard is applicable to all softwood and hardwood timber for structural use.
