Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of
national standards institutes (IS0 member bodies). The work of developing Inter-
national 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 2007 was developed by Technical Committee ISO/TC 45,
Rubber and rubber products.
This second edition was submitted directly to the IS0 Council, in accordance with
clause 5.10.1 of part 1 of the Directives for the technical work of EO. It cancels and
replaces the first edition (i.e. IS0 2007-19751, which had been approved by the
member bodies of the following countries :
Australia Israel Sweden
Austria Italy Switzerland
Egypt, Arab Rep. of Malaysia Turkey
France Netherlands United Kingdom
Germany, F. R. New Zealand USA
Greece South Africa, Rep. of USSR
Hungary Spain
India Sri Lanka
