14、 rights reserved vForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a sub

15、ject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (I

16、EC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical commit

17、tees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be

18、 held responsible for identifying any or all such patent rights. ISO 22966 was prepared by Technical Committee ISO/TC 71, Concrete, reinforced concrete and prestressed concrete, Subcommittee SC 3, Concrete production and execution of concrete structures.

19、rvedIntroduction This International Standard applies to the execution of concrete structures to achieve the intended levels of reliability and serviceability that are given in ISO 2394 3and in standards for the design of concrete structures. This International Standard has three functions: to transf

20、er the requirements set during design from the designer to the constructor, i.e. to be a link between design and execution; to give a set of standardized technical requirements for the execution when ordering a concrete structure; to serve as a check list for the designer to ensure that he provides

21、the constructor with all relevant technical information for the execution of the structure; see Annex A. In order to achieve these objectives, it is necessary that the designer prepare a set of documents and drawings giving all information required for the execution of the work in accordance with th

22、e plans. This set of documents is in this International Standard referred to as the “execution specification”. This International Standard leaves a number of items open that can be decided by the execution specification. It is necessary that the execution specification refer to national provisions i

23、n areas where these apply. It is recognized in this International Standard that areas such as detailed requirements for competence of personnel and details related to quality management are within the competence of the member states. A national annex can refer to national standards approved and publ

24、ished by an ISO member body and that supplement this International Standard; alternatively, the supplementing rules can be given directly in the national annex. INTERNATIONAL STANDARD ISO 22966:2009(E) ISO 2009 All rights reserved 1Execution of concrete structures 1 Scope This International Standard

25、 gives common requirements for the execution of concrete structures and applies to both in-situ works and construction using prefabricated concrete elements. This International Standard requires that the execution specification state all the specific requirements relevant to the particular structure

26、. This International Standard is applicable to temporary as well as permanent concrete structures. Additional or different requirements can be considered and, if required, given in the execution specification when using lightweight aggregate concrete; other materials (e.g. fibres) or constituent mat

27、erials; special technologies/innovative designs. This International Standard does not apply to the following: a) concrete members used only as equipment or construction aids for the execution; b) specification, production and conformity of concrete; c) production of precast concrete elements made in

28、 accordance with product standards; d) safety and health aspects of execution, or third-party safety requirements; e) contractual issues or responsibilities for the identified actions. 2 Normative references The following referenced documents are indispensable for the application of this document.
