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 1496/1 was drawn up by Technical Committee
ISO/TC 104, Freight containers. This second edition was circulated to the Member
Bodies in March 1975.
It has been approved by the Member Bodies of the following countries :
Australia South Africa, Rep. of
Germany
Austria Hungary Spain
Be I g i u m Ireland
Sweden
Brazil Israel Sw i tze r I a nd
Bulgaria Italy Turkey
Canada Mexico
United Kingdom
Czechoslovakia Netherlands
U.S.A.
Denmark New Zealand .S.S. R.
U
Finland Norway Yugoslavia
France Romania
The Member Body of the following country expressed disapproval of the document
on technical grounds :
Japan
This second edition cancels and replaces the first edition (IS0 1496/1-1974).
