Together with BS EN ISO 17760-2:2006 it One of the principal differences between BS 7123 and this standard is that BS 7123 offered more practical guidance on the welding process issues, some of these issues have been highlighted in the Nati

4、onal Annex and further guidance can be found in parts 1 to 3 of BS EN 1011. This standard is best used in conjunction with the National Annexes and the general good practices set out in the BS EN 1011 series.

20、rldwide 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 subject for which a technical committee has been established has the right to be represented o

21、n 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 (IEC) on all matters of electrotechnical standardization. International Standards are drafted

22、 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 committees are circulated to the member bodies for voting. Publication as an International Standa

23、rd 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.

25、cooperation between ISO and CEN (Vienna Agreement). ISO 17660 consists of the following parts, under the general title Welding Welding of reinforcing steel: Part 1: Load-bearing welded joints Part 2: Non load-bearing welded joints Requests for official interpretations of any aspect of this part of I

26、SO 17660 should be directed to the Secretariat of ISO/TC 44/SC 10 via your national standards body. A complete listing of these bodies can be found at www.iso.org. BS EN ISO 17660-1:2006ISO 17660-1:2006(E) vIntroduction Reinforcing steel bars are produced by a number of process routes and usually ha

27、ve a ribbed profile. Taking these issues into account, it is apparent that both the welder and the welding coordinator require a specific level of skill and job knowledge and that special procedures for quality assurance need to be adopted. BS EN ISO 17660-1:2006blank1Welding Welding of reinforcing

28、steel Part 1: Load-bearing welded joints 1 Scope This part of ISO 17660 is applicable to the welding of weldable reinforcing steel and stainless reinforcing steel of load-bearing joints, in workshops or on site. It specifies requirements for materials, design and execution of welded joints, welding

29、personnel, quality requirements, examination and testing. This part of ISO 17660 also covers welded joints between reinforcing steel bars and other steel components, such as connection devices and insert anchors, including prefabricated assemblies. Non load-bearing joints are covered by ISO 17660-2.

30、 This part of ISO 17660 is not applicable to factory production of welding fabric and lattice girders using multiple spot welding machines or multiple projection welding machines. The requirements of this part of ISO 17660 are only applicable to static loaded structures. NOTE For fatigue-loaded stru

31、ctures, depending on type of joint and welding process, it is recommended that an appropriate reduction be taken into account on the fatigue strength of the reinforcing steel. 2 Normative references The following referenced documents are indispensable for the application of this document.
