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, 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 electrotechnicalstandardization. International Standards aredrafted in accordance with therules given in theIsO/IEC Directives,Part2 The main task of technical committees is to prepare International Standards. Draft International Standards adopted bythe technical committees are circulated to the member bodies for voting Publication as an International Standard requires approval by at least 75% of thememberbodies castingavote Attention is drawn to thepossibility that some of the elements of this document may be the subject of patent rights.
