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 SO, 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 6430 was developed by Technical Committee ISO/TC 131,
Fluid power systems, and was circulated to the member bodies in January 1982.
It has been approved by the member bodies of the following countries :
Austria Hungary Romania
Belgium India Spain
Brazil Italy Sweden
Japan United Kingdom
China
Egypt, Arab Rep. of Mexico USA
Netherlands USSR
Finland
France Norway
Germany, F. R. Poland
The member body of the following country expressed disapproval of the document on
technical grounds :
