Precast concrete products - Essential characteristics

This document identifies the essential characteristics of precast concrete products made of reinforced or prestressed normal weight or light weight concrete, used for the frame, foundation, floors, walls, stairs and roofs of building and civil engineering works, and for garages, boundary fences, masts and poles.
This document also covers blocks made of other materials than concrete and intended to be used in concrete beam-and-blocks floor systems.
This document specifies procedures for assessment and verification of constancy (AVCP) of performance of characteristics of those elements.
This document does not cover the following concrete products:
- Masonry and ancillary products,
- Lighting columns and spigots,
- Roof covering products for discontinuous laying,
- Chimney components,
- Products for wastewater treatment,
- Prefabricated reinforced components of autoclaved aerated concrete or light-weight aggregate concrete with open structure,
- Paving units and kerbs,
- Road equipment,
- Elements made with concrete containing more than 1% of homogeneously distributed organic material, by mass or by volume (whichever is the most onerous).
This document does not cover the design, production, handling, installation of the elements and the water tightness of joints between elements.

This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee
CEN/TC 229.

If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations
which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,
Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and
United Kingdom.

Recipients of this draft are invited to submit, with their comments, notification of any relevant patent rights of which they are
aware and to provide supporting documentation.
