FOREWORD
IS0 (the International Organization for Standardization) is a worldwide federation
of national standards institutes (IS0 Member Bodies). The work of developing
is carried out through IS0 Technical Committees. Every
International Standards
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.
Prior to 1972, the results of the work of the Technical Committees were published
as IS0 Recommendations; these documents are now in the process of being
transformed into International Standards. As part of this process, Technical
Committee ISO/TC27 has reviewed IS0 Recommendation R 1017 and found it
technically suitable for transformation. International Standard IS0 101 7 therefore
replaces IS0 Recommendation R 1017-1969 to which it is technically identical.
IS0 Recommendation R 1017 was approved by the Member Bodies of the
following countries :
Australia I ran Spain
Austria Italy Switzerland
Canada Korea, Rep. of Turkey
Czechoslovakia Netherlands United Kingdom
Denmark New Zealand U.S.S.R.
Portugal Yugoslavia
Egypt, Arab Rep. of
France Romania
India South Africa, Rep. of
No Member Body expressed disapproval of the Recommendation.
No Member Body disapproved the transformation of ISO/R 1017 into an
International Standard.
