Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established 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. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
International Standard ISO 61033 was prepared by Technical Committee ISO/TC 29, Small tools, Subcommittee
SC 5, Grinding wheels and abrasives.
This second edition cancels and replaces the first edition (ISO 6103:1986) which has been technically revised.

INTERNATIONAL STANDARD  ISO ISO 6103:1999(E)
Bonded abrasive products — Permissible unbalances of
grinding wheels as delivered — Testing
1 Scope
This International Standard specifies the maximum permissible values of unbalance for various grinding wheels of
ISO 603-1 to ISO 603-9 and ISO 603-12 to ISO 603-16 in the as-delivered condition, with outside diameter equal to
or greater than 125 mm and with a maximum operating speed, v , equal to or greater than 16 m/s.
s
It also specifies the method for measuring the unbalance and the practical method for testing whether a grinding
wheel is acceptable or not.
This International Standard applies to bonded abrasive grinding wheels in the as-delivered condition.
This International Standard does not apply to
 diamond, cubic boron nitride or natural stone grinding wheels;
 centreless control wheels, lapping and disc wheels, ball wheels or glass grinding wheels.
NOTE 1 The values given refer to the grinding wheel itself, independent of any unbalance which may exist in the balancing
arbor or in the means of fastening it to this arbor. These various elements, together with the flanges or hub-flanges, are
assumed to be balanced, homogeneous and free from geometrical defects.
NOTE 2 The effects of unbalance are basically
 additional stresses on the arbor, the machine and its mounting;
 excessive wear of the bearings;
 vibration prejudicial to the quality of machining and increased internal stresses in the grinding wheel;
 increased operator fatigue.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of
this International Standard. For dated references, subsequent amendments to, or revisions of, any of these
publications do not apply. However, parties to agreements based on this International Standard are encouraged to
investigate the possibility of applying the most recent editions of the normative documents indicated below. For
undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC
maintain registers of currently valid International Standards.
