scope:

This European Standard is for prefabricated reinforced components of lightweight aggregate concrete with open structure intended to be used in building constructions: 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 multi layer); - linear components (beams or piers). b) for non-stru ctural 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.
