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 21531:2009(E)
Introduction
Graphical symbols are used in many areas of daily life. They give necessary and useful information of many
kinds in a visual way. They are used as signals (warning or alarm signals), for general information, as a
means of control, for the correct application of machines, instruments, etc. and in may other ways of
communication.
Their content of information is very often superior to verbal explanations because their information is visually
acknowledged instantly and is often kept in memory easier and longer than terms or phonetic explanations.
Graphical symbols are internationally understandable without sometimes difficult, possibly misleading and
costly translations.
Each ISO technical committee is responsible for the selection or creation of graphical symbols within its own
field of interest. Graphical symbols may form the main subject of an International Standard, or a single symbol
or several symbols may appear as part of a standard covering wider aspects of the subject to which the
symbol(s) refer(s).
The ISO Technical Management Board has assigned overall responsibility for standardization in the field of
graphical symbols to ISO/TC 145, Graphical symbols, and to ISO/TC 10/SC 10, Technical product
documentation (tpd) symbols.
ISO/TC 210, Quality management and corresponding aspects for medical devices, which is responsible for
the development of ISO 15233, has prepared an international guide to the development and registration of
symbols for use in the labelling of medical devices. This guideline recommends that the proliferation of
graphical symbols without international harmonization is undesirable and contrary to these objectives.
There is a need for simple, internationally accepted graphical symbols labelling that provide general and
specific information to the user in a manner that overcomes the limitations of languages. It is in the best
interests of safety and health of patients, dentists, dental technicians and other persons, to reduce the
confusion inherent in the use of multiple language labelling. Both of these objectives can be met by the use of
standardized symbols agreed by consensus on an international basis.
The task of determining technical requirements to allow the use of specific symbols is best taken up by bodies
expert in the relevant areas. ISO/TC 106/SC 4/WG 5, Number coding system, has taken up this responsibility
by developing this International Standard.
This International Standard has been prepared to reduce the need for multiple translations of words into
national languages, to simplify labelling whereever possible and to prevent separate development of different
symbols to convey the same information.
This International Standard contains a series of symbols (pictograms) for use in dentistry. Their application
should be considered in the literature, for the labelling and packaging of devices used in dentistry, on items of
dental equipment and instruments. Their use is unlimited and a most helpful means of communication within
dentistry.

INTERNATIONAL STANDARD ISO 21531:2009(E)

Dentistry — Graphical symbols for dental instruments
1 Scope
This International Standard presents a series of graphical symbols for dental instruments. They are set out
particularly for this area of dentistry or corresponding specific areas within dentistry. General symbols are
taken from relevant ISO, IEC or other international documents. Several new symbols presented by
manufacturers or users have been added.
Because many dental products are considered in some cases as medical devices and in some cases not as
medical devices, in dentistry the restricted usage of the symbols specified in ISO 15223 is considered as not
practical. It is the intention of this International Standard to expand the application area of some graphical
symbols specified in ISO 15223 to the whole area of dentistry. Therefore these symbols are listed in this
International Standard together with their source document.
NOTE In addition to terms used in two of the three official ISO languages (English, French and Russian), this
International Standard gives the equivalent terms in the German language; these are published under the responsibility of
the member body for Germany (DIN). However, only the terms given in the official languages can be considered as
ISO terms.
