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 IsocollaboratescloselywiththeInternationalElectrotechnicalCommission(lEC)onallmattersof electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the Iso/IEC Directives, Part 1.
