FOREWORD
IS0 (the International Organization for Standardization) is a worldwide federation
(IS0 Member Bodies). The work of developing
of national standards institutes
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 2262 was drawn up by Technical Committee
ISO/TC 1 1 1, Round steel link chains, chain wheels, lifting hooks and accessories.
It was approved in July 1971 by the Member Bodies of the following countries:
Chile Israel Romania
Egypt, Arab Rep. of Italy Spain
France Sweden
Japan
India Korea, Rep. of Turkey
Ireland Netherlands United Kingdom
The Member Bodies of the following countries expressed disapproval of the
document on technical grounds:
Australia New Zealand Y
Austria South Africa, Rep. of
Belgium
