External wall functions could be:
   thermal insulation (see 3.11.1);
   sound insulation (see 3.11.2);
   hygrometric control (see 3.11.3);
or a combination of these.
They may be plain, reinforced or prestressed. They may be loadbearing or not.
These include:
   solid walls;
   composite walls;
   sandwich walls;
   lightened walls;
   claddings.
The wall element may also work as a column or beam.

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 2007, and conflicting national standards shall be withdrawn at the latest by April 2010. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Construction Products Directive(s) (89/106/EEC). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. This document is one of a series of product standards for precast concrete products. For common aspects reference is made to EN 13369: Common rules for precast concrete products, from which also the relevant requirements of the EN 206-1: Concrete — Part 1: Specification, performance, production and conformity are taken. The references to EN 13369:2004 by CEN/TC 229 product standards are intended to make them homogeneous and to avoid repetitions of similar requirements. Eurocodes are taken as a common reference for design aspects. The installation of some structural precast concrete products is dealt with by ENV 13670-1: Execution of concrete structures — Part 1: Common rules, which has at the moment the status of a European Prestandard. In all countries it can be accompanied by alternatives for national application and it should not be treated as a European Standard. The programme of standards for structural precast concrete products comprises the following standards, in some cases consisting of several parts: EN 1168, Precast concrete products — Hollow core slabs. EN 12794, Precast concrete products — Foundation piles. EN 12843, Precast concrete products — Masts and poles. EN 13224, Precast concrete products — Ribbed floor elements. EN 13225, Precast concrete products — Linear structural elements. EN 13693, Precast concrete products — Special roof elements. EN 13747, Precast concrete products — Floor plates for floor systems. EN 13978, Precast concrete products — Precast concrete garages. EN 14843, Precast concrete products — Stairs. EN 14844, Precast concrete products — Box culverts.

4 EN 14991, Precast concrete products — Foundation elements. EN 14992, Precast concrete products — Wall elements. prEN 15037, Precast concrete products - Beam-and-block floor systems. EN 15050, Precast concrete products — Bridge elements. prEN 15258, Precast concrete products — Retaining wall elements. This standard defines in Annex ZA the application methods of CE marking to products designed using the relevant EN Eurocodes (EN 1992-1-1 and EN 1992-1-2). Where, in default of applicability conditions of EN Eurocodes to the works of destination, design Provisions other than EN Eurocodes are used for mechanical strength, the conditions to affix CE marking to the product are described in ZA.3.4. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

6 1 Scope This European Standard applies to prefabricated walls, made of normal weight or lightweight concrete with dense structure. They may have external wall functions (see 3.11) or not, have facing functions (see 3.12) or not or have a combination of these functions. External wall functions could be:  thermal insulation (see 3.11.1);  sound insulation (see 3.11.2);  hygrometric control (see 3.11.3); or a combination of these. They may be plain, reinforced or prestressed. They may be loadbearing or not. These include:  solid walls;  composite walls;  sandwich walls;  lightened walls;  claddings. The wall element may also work as a column or beam. 2 Normative references The following referenced documents are indispensable for the application of this document.

In general the term “product” refers to an element which is produced in large numbers. For general terms see Clause 3 of EN 13369:2004.

EXAMPLE Façade panels and parapets excluding small cladding panels) 3.3 non loadbearing wall wall which carries only its self weight and is not necessary for the building stability or important for the safety of people 3.4 solid wall precast wall of any shape produced as one solid unit including reinforcement and fixtures NOTE See Figure 1 3.5 composite wall composite wall consisting of two precast reinforced layers which are joined together with a gap by means of a lattice girder system. NOTE 1 See Figure 2 NOTE 2 On site, the space between the layers is filled with concrete. Composite walls may also consist of a shell with lattice girders with the other side limited by an existing wall or another formwork during the erection 3.6 sandwich wall consists of a base panel, a thermal insulation layer, a possible air space and a facing panel. NOTE 1 see Figure 3 NOTE 2 The layers may be connected stiffly or to allow relative in plane displacement between the layers 3.6.1 facing panel outermost layer of a sandwich wall element 3.6.2 base panel structural layer of a sandwich element NOTE It transfers its own dead load and the load from the facing panel to the structure. It may also transfer load from other members 3.7 lightened wall wall produced in the precasting plant as a complete unit NOTE 1 see Figure 4 NOTE 2 It may consist of two external concrete layers and internal blocks of light weight materials (for example foam polystyrene, polyurethane) or hollow-core

8 3.8 cladding non loadbearing panel fixed to the structure by means of connecting systems NOTE 1 see Figure 5 NOTE 2 An insulating system may be inserted between this panel and the loadbearing structure 3.9 small cladding cladding element without reinforcement with a maximum size of 2,25 m2, a maximum length of 1,5 m and a thickness smaller than 80 mm 3.10 plain concrete element structural concrete elements having less reinforcement than the minimum reinforcement according to the relevant design code EXAMPLE EN 1992-1-1:2004, Clause 9.6 3.11 external wall functions 3.11.1 thermal insulation capacity to limit the transfer of thermal flow 3.11.2 sound insulation capacity to reduce the transmission of sound 3.11.3 hygrometric control capacity to avoid the forming of condensate in the wall construction and particularly in the insulating materials which are frequently hygroscopic 3.12 facing function capacity to satisfy special dimensional requirements, esthetical surface requirements, esthetical shape requirements, or a combination of these
