Foreword
ISO (the International Organization for S t a n d a r d i z a t i o n ) i s a worldwide federation of national
standards bodies (ISO member bodies). 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 electrotechnical standardization.
