29、/TC 229-CEN/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 September 2012, and conflicting national standards shall be withdra
30、wn at the latest by September 2012. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate gi
31、ven to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. This document includes Amendment 1, approved by CEN on 2
32、012-01-23. This document supersedes EN 15050:2007. The start and finish of text introduced or altered by amendment is indicated in the text by tags ! “. 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
33、 for precast products, from which also the relevant requirements of the EN 206-1: Concrete Part 1: Specification, performances, production and conformity are taken. The references to EN 13369 by CEN/TC 229 product standards are intended to make them homogeneous and to avoid repetitions of similar re
34、quirements. 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
35、it can be accompanied by alternatives for national application and it shall 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 Holl

For design ru
43、les and resistance to fire reference is made to EN 1992-1-1 and EN 1992-1-2. Additional complementary rules are provided where necessary. In 4.3.3 and 4.3.4 this European Standard includes specific provisions resulting from the application of EN 1992-1-1, EN 1998-1, EN 1992-1-2 and EN 1992-2 rules m
44、ade specific for the concerned product. The use of these provisions is consistent with a design of works made with EN 1992-1-1, EN 1992-1-2, and EN 1992-2.

45、ral elements produced in a factory and used in bridge construction, such as deck elements.“ Normal weight concrete elements are considered, both reinforced and prestressed; their use can be on road bridges, railway bridges and footbridges. Deck elements include both single elements from which the de
46、ck may be composed (beams, slabs, ribbed or cellular elements) and elements consisting of a segment of the entire deck. !deleted text“ Some examples of elements dealt with are shown in Annex A. The durability aspects are also considered. This European Standard makes reference to precast elements pro
47、duced in a factory or near the construction site in a place protected from adverse weather conditions. It is assumed that if the elements are not manufactured in a factory, the production conditions assure the same level of quality control as in a factory. It is assumed that the production place is
48、protected from rain, sunshine and wind. Some of the elements are also treated in other European Standards (e.g. beams, slabs). This European Standard deals with the specific aspects related to the use of these elements in bridge construction. !Foundation piles, piers, abutments, barriers, bumpers, guards, arches and“ box culverts are out the scope of this European Standard. 2 Normative references The following referenced documents are indispensable for the application of this document.
