The work of preparing International Standards is normall
9、y 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, governmental and non-governmental, in liaison with ISO, also take part in the
10、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 Directives, Part 3. Draft International Standards adopted by the technical
11、 committees 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 International Standard may be the subject of patent rig
12、hts. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 14655 was prepared by Technical Committee ISO/TC 17,Steel, Subcommittee SC 16, Steels for the reinforcement and prestressing of concrete. Annexes A and B form a normative part of this Int
13、ernational Standard. Annex C is for information only.
