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.
