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 are drafted in accordance withthe rules given in the ISo/IEC Directives, 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. Publicationas an International Standard requires approvalbyat least75% of thememberbodies castinga 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 beheld responsible for identifying any or all such patent rights.
