24、 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 subject for which a technical committee has been established has the right to be repre
25、sented 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 (IEC) on all matters of electrotechnical standardization. International Standards are
26、 drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. 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 bodies casting a
27、vote. Attention is drawn to the possibility that some of the elements of this part of ISO 8205 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 8205-1 was prepared by Technical Committee ISO/TC 44, Weldin
