FOREWORD
IS0 (the International-Organization for Standardization) is a worldwide federation
of national standards institutes (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 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.
Prior to 1972, the results of the work of the Technical Committees were published
as IS0 Recommendations; these documents are now in the process of being
transformed into International Standards. As part of this process, Technical
Committee lSO/TC 29 has reviewed IS0 Recommendation R 1117 and found it
technically suitable for transformation. International Standard IS0 1117 therefore
replaces IS0 Recommendation R 11174969 to which it is technically identical.
IS0 Recommendation R 1117 was approved by the Member Bodies of the
following countries :
Sweden
Australia Israel
Switzerland
Belgium Italy
Thailand
Czechoslovakia Japan
Turkey
Egypt, Arab Rep. of Netherlands
United Kingdom
France New Zealand
U.S.A.
Germany Peru
U.S.S.R.
Greece Poland
Yugoslavia
Hungary Portugal
India South Africa, Rep. of
Ireland Spain
No Member Body expressed disapproval of the Recommendation.
The Member Bodies of the following countries disapproved the transformation of
lSO/R 1117 into an International Standard :
Austria
Sweden
Switzerland

3.2 Drillings
The following drawings correspond to the drillings and to the boring of the fixing plate seen from the face.
Some of the nuts may be omitted in the wheels but it is recommended that such as are used should correspond to one point
of the drillings provided for.
For wheels with a diameter D of 300, 350, 400,450, 500, 600 and 750 mm, or of 12, 14, 16, 18, 20, 24 and 30 in, the nuts
are equally spaced on the corresponding circle.
The dimensions of the nuts shall be indicated on the wheels.
* Dimensions not included in IS0 525.
