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.
Prior to 1972, the results of the work of the technical committees were published
as IS0 Recommendations; these documents are in the process of being transformed
into International Standards. As part of this process, Technical Committee
ISOflC 45, Rubber and rubber products, has reviewed IS0 Recommen-
R 1629-1971 and found it technically suitable for transformation.

International Standard IS0 1629 therefore replaces IS0 Recommen-
dation R 1629-1971 (incorporating amendments approved in 1974 and 19761, to
