scope:

This standard specifies performance requirements for wood-based prefabricated load bearing compound elements (wall, floor and roof elements) consisting of joists from wood and/or wood based materials and one or both sided panels or boards connected to the joists by suitable fixation. The cavities of the elements may be filled entirely or partially with insulating materials. The exterior faces of the panels or boards can also be covered with insulation material. This standard also specifies requirements for the components and minimum requirements for the production of such elements.
