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 1.90, 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
IS0 Council.
Standards by the
International Standard IS0 3759 was drawn up by Technical Committee
ISO/TC38, Textiles, and was circulated to the Member Bodies in May 1975.
It has been approved by the Member Bodies of the following countries :
Australia Germany South Africa, Rep. of
Belgium Hungary
Sweden
Brazil Ireland
Switzerland
Bulgaria Israel
Turkey
Canada Japan United Kingdom
Czechoslovakia Netherlands U.S.A.
Denmark New Zealand U.S.S.R.
France Poland Yugoslavia
