IS0 (the lnternational 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 6749 was developed by Technical Committee ISO/TC 127,
Earth-moving machinery, and was circulated to the member bodies in October 1979.
It has been approved by the member bodies of the following countries :
Australia Finland Romania
Austria France South Africa, Rep. of
Belgium Germany, F.R. Sweden
Bulgaria Italy United Kingdom
Chile USA
Czechoslovakia Poland USSR
No member body expressed disapproval of the document.
