The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a

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 matte
