This document covers, regardless of if manufactured in factories or in temporary plants on site under the same conditions, precast concrete elements made of lightweight concrete with an open structure, and with a dry density between 400 and 2000 kg/m3, intended to be used as structural element: — solid, hollow core and multilayer load-bearing wall elements; — retaining wall elements, excluding retaining walls intended to retain tanks or reservoirs of liquids and diaphragm walls (concrete sheet piling); — solid, hollow core and multilayer roof elements, excluding ribbed floor elements and floor slabs elements; — solid, hollow core and multilayer floor elements excluding floor elements with the intended use to carry traffic loads; — solid and hollow core beams; — solid piers. This document covers, regardless of if manufactured in factories or in temporary plants on site under the same conditions, precast concrete elements made of lightweight concrete with an open structure, and with a dry density between 400 and 2000 kg/m3, intended for not to be used as structural use: — solid, hollow core and multilayer non-load-bearing wall elements; — cladding elements; — rectangular cross-section box culverts; — components for noise barriers. NOTE In addition to their loadbearing and encasing function, elements can also be used to provide fire resistance, sound insulation and thermal insulation. Recycled lightweight concrete with an open structure (other than closed-loop recycling during production) is covered by this document.
