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 liaison with IsO, also take part in the work. IsO collaborates closely with the International Electrotechnical Commission(IEC)onall mattersof electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/lE Directives, Part 3 The main task of technical committees is to prepare International Standards. Draft International Standards adopted Standard requires approvalbyat least 75%of thememberbodies castinga vote. patent rights.
