FOREWORD
IS0 (the International Organization for Standardization) is a worldwide federation
of national standards institutes (IS0 Member Bodies). The work of developing
International Standards is carried out through IS0 Technical Committees. Every
Member Body interested in a subject for which a Technical Committee has been set
up 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.
Draft International Standards adopted by the Technical Committees are circulated
to the Member Bodies for approval before their acceptance as International
Standards by the IS0 Council.
International Standard IS0 2031 was drawn up by Technical Committee
ISO/TC 87, Cork.
It was approved in November 1970 by the Member Bodies of the following
countries:
Bulgaria Iran Spain
Czechoslovakia Italy U.A.R.
France Portugal United Kingdom
Greece South Africa, Rep. of
No Member Body opposed the approval of the Draft.
