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 IsoO, also take part in the work. ISo collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnicalstandardization.
