18、er 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 on that committee. International organizations, government
19、al 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 in accordance with the rules given in the ISO/IEC Direct
20、ives, 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 Standard requires approval by at least 75 % of the member bodie
21、s 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 held responsible for identifying any or all such patent rights. ISO 17660-1 was prepared by the European Committee for Standardization (CEN) Techni
22、cal Committee CEN/TC 121, Welding, in collaboration with Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee SC 10, Unification of requirements in the field of metal welding, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

27、E) ISO 2006 All rights reserved 1Welding Welding of reinforcing 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 requirement
28、s for materials, design and execution of welded joints, welding 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
29、 assemblies. Non load-bearing joints are covered by ISO 17660-2. 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 appl
30、icable to static loaded structures. NOTE For fatigue-loaded structures, 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 ar
