This document specifies material, product and documentation requirements for prefabricated structural members (e. g. trusses for roofs, walls and floors, frames, composite beams and girders) for use in buildings made from structural timber according to EN 14081-1 with or without finger joints assembled with punched metal plate fasteners. The standard also covers tests and/or calculation methods to carry out the evaluation of conformity and requirements for the marking of these members. As regard resistance to biological organisms, this standard covers prefabricated structural members manufactured from either untreated timber or timber treated to improve its natural durability. This standard does not cover prefabricated timber structural members intended to be used in constructions under predominantly dynamic loads (e. g. bridges) or for use in unprotected external conditions (i.e. use class 3 in accordance with EN 335-1). Furthermore, it does not cover members treated to improve their fire performance.
