Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of
national standards bodies (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 authorized has the
right to be represented on that committee. International organizations, governmental
J
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 565 was developed by Technical Committee ISO/TC 24,
Sieves, sieving and other sizing methods, and was circulated to the member bodies in
July 1982.
It has been approved by the member bodies of the following countries :
Australia India South Africa, Rep. of
Belgium Italy Spain
Canada Mexico Switzerland
Egypt, Arab Rep. of Norway United Kingdom
France Portugal USA
Germany, F. R. Romania USSR
No member body expressed disapproval of the document.
This second edition cancels and replaces the first edition (i.e. IS0 5651972).
