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 org
25、anizations, 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.Draft International Standards adopted by the technical committees are c
