Structural timber. Strength classes Ingestion-build-264231 Smoke and heat control systemsThis European Standard establishes a system of strength classes for general use in structural codes. It provides 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 applies to all softwood and hardwood timber for structural use.
