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 3823-2 was prepared by Technical Committee ISO/TC 106, Dentistry, Subcommittee SC 4, Dental
instruments.
This second edition cancels and replaces the first edition (ISO 3823-2:1986), which has been technically
revised to contain the updated specifications for dental steel and carbide finishing burs. The specifications for
steel finishing burs remain unchanged, while those for carbide finishing burs have been updated and changed
in respect to bur shapes and diameters.
ISO 3823 consists of the following parts, under the general title Dentistry — Rotary bur instruments:
 Part 1: Burs
 Part 2: Finishing burs

ISO 3823-2:2003(E)
Introduction
This part of ISO 3823 is one of a series of International Standards relating to dental rotary instruments.
This second edition of ISO 3823-2 contains the updated specifications for tungsten carbide finishing burs. The
specifications for steel finishing burs remain unchanged.
The various dimensional and other requirements specified for steel and carbide finishing burs are those
considered important to ensure the interchangeability and safe usage of these instruments in the practice of
dentistry.
The nominal diameters of the working parts listed in Tables 1 to 68 comply with the diameters specified in
ISO 2157.
Attention is drawn to the ISO 6360 series, which specifies a 15-digit numbering system for the identification of
dental rotary instruments of all types.

INTERNATIONAL STANDARD ISO 3823-2:2003(E)

3 Classification
Steel and carbide finishing burs shall be classified, according to the material of the working part, into the
following two types:
 Type 1: Steel finishing burs
 Type 2: Carbide finishing burs
4 Symbols
For the purposes of this part of ISO 3823, the following symbols apply:
d diameter of working part, head diameter;
d neck diameter;
ISO 3823-2:2003(E)
d diameter of tip;
l length of working part, head length;
l overall length;
α angle of the working part.
5 Requirements
5.1 Material
5.1.1 Working part
The working parts of steel finishing burs shall be made of steel and those of carbide finishing burs of tungsten
carbide. The selection of the type of material and its treatment shall be left to the discretion of the
manufacturer.
5.1.2 Shank
The material of the shank shall comply with ISO 1797-1.
5.2 Shape
The shape of the working part shall be as specified in Figures 1 to 34. Variations of the shape within the
limited dimensions and the terms specified in the titles of the respective subclauses are permitted.
Testing shall be carried out in accordance with 6.1.
5.3 Dimensions and number of blades
5.3.1 Units used for dimensions and angles
Dimensions are given in millimetres, angles are given in degrees.
5.3.2 Working part
The dimensions of the working part shall be as specified in Tables 1 to 34.
The number of blades shall be as specified in Tables 1 to 34. The numbers refer to instruments with medium
(standard) fineness.
The toothing shown in Figures 1 to 34 are examples only. Toothing shall be at the discretion of the
manufacturer. The identification of the toothing shall be made in accordance with ISO 6360-3.
Testing shall be carried out in accordance with 6.2.
5.3.3 Shank
The shank shall be Type 1, 2 or 3 in accordance with ISO 1797-1.
5.3.4 Overall length
The overall length of the instrument, l , depends on the fitting length of the shank used.
2 © ISO 2003 — All rights reserved

ISO 3823-2:2003(E)
In Tables 1 to 34 the term “Standard” refers to instruments with standard fitting lengths of the shanks.
For instruments with longer or shorter shank length, the overall length, l , varies accordingly. See
ISO 1797-1:1992, Table 1, for fitting length of shanks.
Testing shall be carried out in accordance with 6.2.
