Foreword
ISO (the International Organization for Standardization) is a worldwide federation of
national Standards institutes (ISO member bedies). The work of developing Inter-
national Standards is carried out through ISO 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 ISO Council.
International Standard ISO 6948 was developed by Technical Committee ISO/TC 153,
Valves, and was circulated to the member bodies in November 1979.
