The work of developing International Standards is carried out through Iso Technical Committees. Every Member Body interested in a subject for which a Technical Cormmittee has been set governmental and non governmentai, in liaison with IsO, also take part in the work. Draft International Standards adopted by the Technical Committees are circulated to the Member Bodies for approval before their acceptance as international Standards by the Iso Council. International Standard Iso 2445 was drawn up by: Technica! Committee isO.rc 59, Building construction. It was approved in Novembet 1971 by the Member Bodies ot the tollowing countries : Belgium Hungary Romania Canada Ireland South Africa, Rep. ot Chile Israel Spain Czechoslovakia Italy Sweden Denmark Netherlands Switzerland Turkey Egypt, Arab Rep. of New Zealand Finland Norway United Kingdom Poiand Germany U.S.S.R. The Member Body of the following country expressed disapproval of the document on technical grounds : France Other IsO documents to be consulted : ISO/R 1791, Modular co-ordination - Vocabulary. ISO/R 1803, Tokerances for buiding -- Vocabulary. ISO 2444, Joints in building - Vocabulary. (At present at the stage of draft.)
