21、ld by AFNOR. 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of an identical text or by endorsement, at the latest by May 2012, and conflicting national standards shall be withdrawn at the latest by August 2013. Attention is drawn to the possibility tha
22、t 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 supersedes EN 13224:2004+A1:2007. Significant technical changes compared to the previous version are: a) change i
23、n the scope to also cover elements with bottom slab (as shown in Annex A); b) deletion of the requirement on planarity (in 4.3.1.1 and 5.2); c) deletion of the requirement on camber or sag (in 4.3.1.1 and 5.2); d) addition of a rule for elements without shear reinforcement in 4.3.3.3; e) adoption of
24、 the new template for Annex ZA. 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 the Construction Products Directive (89/106/EEC) of the European Union (EU). For relationship with E
25、U Directive(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: Common rules for precast products, from which also the relevant requirements o
26、f 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 requirements. Eurocodes are taken as a common reference for design a
27、spects. The installation of some structural precast concrete products is dealt with by EN 13670:2009 Execution of concrete structures.

35、ntroduction 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 and resistance to fire, reference is made to EN 1992-1-1 and EN 1992-1-2. Ad
36、ditional complementary rules are provided where necessary. 4.3.3 and 4.3.4 include specific provisions resulting from the application of EN 1992-1-1, and EN 1992-1-2 rules made specific for the concerned product. The use of these provisions is consistent with a design of works made with EN 1992-1-1
37、and EN 1992-1-2.

38、eria and evaluation of conformity for precast ribbed elements made of reinforced or prestressed normal weight concrete, used in floors or roofs. The elements consist of a top and/or bottom slab and one or more (usually two) ribs; transverse ribs may also be present. Some examples of precast elements
39、 considered in this document are shown in Annex A. Specific requirements for minor floor elements are listed in Annex B. This document covers terminology, performance criteria, tolerances, relevant physical properties, test methods and aspects of transport and erection. This document does not cover
40、load-bearing capacity determined by testing. 2 Normative references The following referenced documents are indispensable for the application of this document.
