Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
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, govern-
mental and non-governmental, in liaison with ISO, also take part in the
work. IS0 collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an Inter-
national Standard requires approval by at least 75 % of the member
bodies casting a vote.
International Standard IS0 7711-3 was prepared by Technical Committee
ISO/TC 106, Dentistry, Sub-Committee SC 4, Dental instruments.
IS0 7711 consists of the following parts, under the general title Dental
rotary instruments - Diamond instruments:
- Part I: Shapes, main dimensions and requirements
- Part 2: Discs
- Part 3: Grit sizes, designation and co/our code
IS0 7711:1984 is considered as part 1 of this series.
