19、Technical Committee CEN/TC 104 “Concrete and related products”, the secretariat of which is held by DIN. 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 June 2010, and conflicting national standar
20、ds shall be withdrawn at the latest by June 2010.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 subject 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
21、:2000. 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). Because of the close connection between design rules and rules for execution, CEN/TC 104/SC 2 has developed
22、this standard in liaison with CEN/TC 250/SC 2, and CEN TC 229 According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finlan
23、d, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. . EN 13670:2009 (E) 6 Introduction This European Standard applies to the executio
24、n of concrete structures to achieve the intended level of safety and serviceability during its service life, as 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
25、 Nationally Determined Parameters (NDPs) applicable in the place of use. This European Standard has three functions: 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 ex
26、ecution when ordering a concrete structure; c) to serve as a check list for the designer to ensure that he provides 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 docu
27、ments and drawings giving all information required for the execution of the work in accordance with the plans. This 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.
28、In areas where national provisions shall apply these should be referred to in the execution specification. It is 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 M
29、ember States. If the national CEN member publishes a National Annex to this standard, it may refer to national standards 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
30、A detailed overview of the system of European Standards related to concrete works is shown in Figure 1. Figure 1 System of European Standards as basis for design, execution and materials selection for concrete works (only main modules) EN 13670:2009 (E) 7 1 Scope (1) This European Standard gives com
31、mon requirements for execution of concrete structures, it applies to both in-situ works and construction using prefabricated concrete elements. (2) This standard expects the execution specification to state all the specific requirements relevant to the particular structure. (3) This standard is appl
32、icable to permanent as well as temporary concrete structures. (4) Additional or different requirements should be considered and, if required, given in the execution specification when using: a) lightweight aggregate concrete; b) other materials (e.g. fibres) or constituent materials; c) special tech
33、nologies/innovative designs. (5) This standard does not apply to concrete members used only as equipment or construction aids for the execution. (6) This standard does not cover the specification, production and conformity of concrete. (7) This standard is not applicable to the production of precast
34、 concrete elements made in accordance with product standards. (8) This standard does not cover safety and health aspects of execution, or third party safety requirements. (9) This standard does not cover contractual issues or responsibilities for the identified actions. NOTE It is within the concept
35、 of this standard that supplementing requirements can be given for the individual project in the execution specification, on a national level in a national annex, or on a general basis in European standards for special applications e.g. standards for special geotechnical works. 2 Normative reference
