International organizations, govern- mental 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:Internationalstandardsadoptedbythetechnicalcommitteesare circulated to the member bodies for voting.Publlcation as an Interna- tional Standard requires approval byatleast 75% of the member bodies casting a vote.
