NEN-EN 1520:2011 en

This European Standard is for prefabricated components of lightweight aggregate concrete (LAC) with open structure and with structural or non-structural reinforcement intended to be used in building construction a) for structural elements: - loadbearing wall components (solid, hollow core or multilayer); - retaining wall components (solid) with or without surcharge loading; - roof components (solid, hollow core or multilayer); - floor components (solid, hollow core or multilayer); - linear components (beams or piers). b) for non-structural elements: - non-loadbearing wall components (e.g. for partition walls); - cladding components (without fixtures) intended to be used for external facades of buildings; - small box culverts used to form channels for the enclosure of services; - components for noise barriers. Components covered by this European Standard are only intended to be subjected to predominantly non-dynamic actions, unless special measures are introduced in the relevant clauses of this European Standard. The term "reinforced" relates to reinforcement used for both structural and non-structural purposes.
