BS EN 845-2:2013+A1:2016

This European Standard specifies requirements for prefabricated lintels for maximum spans of 4,5m and made from steel, autoclaved aerated concrete, manufactured stone, concrete, fired clay units, calcium silicate units, natural stone units, or a combination of these materials. Concrete and steel beams conforming to EN1090‑1 , EN12602 and EN13225 , as appropriate, are not covered by this standard. Prefabricated lintels can be either complete lintels or the prefabricated part of a composite lintel. This European Standard is not applicable to: lintels completely made on site; lintels of which the tensile parts are made on site; timber lintels; natural stone lintels, not reinforced. Linear components spanning clear openings greater than 4,5m in masonry walls and linear components intended for use independently in a structural role (e.g. beams) are not covered by this standard.
