The date of applicability of EN 14992 as a harmonized European Standard, i.e. the date after which this standard may be used for CE marking purposes, is subject to an announcement in the Official Jo

The Commission in consultation with Member States has agreed a transition period for the co-existence of harmonized European Standards and their corresponding national standard(s). It is intended that this period will comprise a period, usually nine months, after t

At the end of this co-existence period, the national standard(s) will be withdrawn. EN

EN 14992:2007(E) 3 Foreword This document (EN 14992:2007) has been prepared by Technical Committee CEN/TC 229 “ Precast concrete products” , the secretariat of which is held by AFNOR and was examined by and agree
18、d with a joint working party appointed by the Liaison Group CEN/TC 229-TC250, particularly for its compatibility with structural Eurocodes. 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
19、2007, and conflicting national standards shall be withdrawn at the latest by April 2010.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) (89/1
20、06/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, fro
21、m 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
22、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
23、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 127
24、94, Precast concrete products Foundation piles. EN 12843, Precast concrete products Masts and poles. EN 13224, Precast concrete products Ribbed floor elements.

EN 14992:2007(E) 5 Introduction The evaluation of conformity given in this standard refers to the completed precast elements which are supplied to the market and covers all the production operations carried out in the factory. For design rules reference is made to EN 1992-1-1. Additiona

EN 14992:2007(E) 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
32、 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
33、 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 docume
34、nt. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
