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 2.
The main task of technical committees is to prepare International Standards. 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.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 21671 was prepared by Technical Committee ISO/TC 106, Dentistry, Subcommittee SC 4, Dental

Introduction
This International Standard is one of a series of standards relating to rotary instruments used in dentistry.
The various dimensional and other requirements specified for polishers are those considered important to
ensure the interchangeability and safe usage of these instruments in the dental laboratory and at the dentist's
working place.
The nominal diameters of the working part listed in Clauses 5 and 6 comply preferably with the diameters
specified in ISO 2157.
Attention is drawn to ISO 6360 which specifies a 15-digit number coding system for the identification of rotary
instruments of all types used in dentistry.
