Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of
national standards institutes (IS0 member bodies). The work of developing Interna-
IS0 technical committees. Every member body
tional Standards is carried out through
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 2632/111 was developed by Technical Committee
ISO/TC 57, Metrology and properties of surfaces, and was circulated to the member
bodies in March 1978.
It has been approved by the member bodies of the following countries :
France Romania
Australia
Austria Germany, F. R. South Africa, Rep. of
Hungary Spain

Brazil Japan Switzerland
Bulgaria Mexico Turkey
