Timber structures - Product requirements for prefabricated structural members assembled with punched metal plate fasteners

This document specifies product requirements for prefabricated structural members (e.g. trusses, beams and girders) for use in buildings and bridges made from members of structural timber (with or without finger joints) assembled with punched metal plate fasteners.
The standard also covers methods to carry out the evaluation of conformity and the marking.
