14、onal 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 on that committee. Internat

15、ional 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 in accordance with the ru

16、les given in the ISO/IEC Directives, Part 3. 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

17、 least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this part of ISO 9093 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 9093-2 was prepared by Technical Committ
