19、ducts”, the secretariat of which is held by AFNOR, and was examined by and agreed with a joint working party appointed by the Liaison Group CEN/TC 229-CEN/TC 250, particularly for its compatibility with structural Eurocodes. This European Standard shall be given the status of a national standard, ei

20、ther by publication of an identical text or by endorsement, at the latest by April 2009, and conflicting national standards shall be withdrawn at the latest by July 2010. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or

21、CENELEC shall not be held responsible for identifying any or all such patent rights. 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 EC Directive(s). For relationship with EC Direc

22、tive(s), see informative Annex ZA, which is an integral part of this document. This standard is one of a series of product standards for precast concrete products. For common aspects reference is made to EN 13369:2004: Common rules for precast products, from which also the relevant requirements of t

23、he EN 206-1: Concrete Part 1: Specification, performances, 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

24、 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 an European prestandard. In all countries it can be accompanied by alternatives for national application

25、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 on several parts: EN 1168, Precast concrete products Hollow core slabs EN 12794, Precast concrete products Foundation pi

31、EN 1992-1-1:2004 and EN 1992-1-2:2004). 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 and Z.A 3.5.

34、he evaluation of conformity given in this standard refers to the 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 1992-1-1:2004. Additional complementary rules are provided where necessary.

35、 Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 17/12/2009 02:03, Uncontrolled Copy, (c) BSIBS EN 15258:2008EN 15258:2008 (E) 7 1 Scope This European Standard deals with the requirements, the basic performance criteria and evaluation of conformity for precast elements made of plain, reinforc

36、ed or prestressed normal weight concrete, used for the construction of retaining walls. The products covered by this European Standard are intended to be used as part of retaining walls in applications such as: to retain natural ground excavations and trenches; to retain earth fills for roads, platf

37、orms, etc.; in bridge abutments and their flank walls; to retain several kinds of loose materials such as sand, gravel, etc. Some examples of precast elements considered in this European Standard are shown in the Informative Annex B. The products may be used in seismic areas on condition that they f

38、ulfil the requirements specific to this use. This European Standard does not cover: products for retaining walls of tanks or reservoirs of liquids; retaining wall elements up to a height of 1,0 m and those assembled to form retaining walls of up to 1,0 m in height (e.g. stacked flower boxes for dwar

39、f walls) if the corresponding retaining wall is used for secondary loads (max. horizontal earth fill and with light surcharge); products for stacked planting boxes, having only faade functions, and therefore not submitted to any loads (such as earth pressure loads, highway load effects, etc.); preca

40、st diaphragm walls (concrete sheet piling). 2 Normative references The following referenced documents are indispensable for the application of this document.
