This European Standard shall be given t
30、he status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2010, and conflicting national standards shall be withdrawn at the latest by June 2010. Attention is drawn to the possibility that some of the elements of this document may be the su
31、bject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes ENV 13670-1:2000. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supp
32、orts essential requirements of EC Directive(s). Because of the close connection between design rules and rules for execution, CEN/TC 104/SC 2 has developed this standard in liaison with CEN/TC 250/SC 2, and CEN TC 229 According to the CEN/CENELEC Internal Regulations, the national standards organiza
33、tions 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, Roman

35、given by EN 1990, Eurocode Basis of structural design, EN 1992, Eurocode 2 Design of concrete structures and EN 1994, Eurocode 4 Design of composite steel and concrete structures, with the Nationally Determined Parameters (NDPs) applicable in the place of use. This European Standard has three functi
36、ons: a) to transfer the requirements set during design to the constructor i.e. to be a link between design and execution; b) to give a set of standardized technical requirements for the execution when ordering a concrete structure; c) to serve as a check list for the designer to ensure that he provi
37、des the constructor with all relevant technical information for the execution of the structure (see Annex A). In order to achieve these objectives, the design shall result in a set of documents and drawings giving all information required for the execution of the work in accordance with the plans. T
38、his set of documents is, in this European Standard, referred to as the “execution specification“. This standard leaves a number of items open to be decided in the execution specification. In areas where national provisions shall apply these should be referred to in the execution specification. It is
39、 recognised in this European Standard that areas such as detailed requirements for competence of personnel, and details related to the Quality Management are within the competence of the Member States. If the national CEN member publishes a National Annex to this standard, it may refer to national s
40、tandards approved and published by the CEN member or national provisions, which supplement this standard, alternatively the supplementing rules can be given directly in the National Annex A detailed overview of the system of European Standards related to concrete works is shown in Figure 1.
