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. Esch 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. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the ISO Council. They are approved in accordance with ISO procedures requiring at least 75 % approval by the member bodies voting. International Standard ISO 3823/2 was prepared by Technical Committee ISO/TC 106, Dentistry. Users should note that all International Standards undergo revision from time to time and that any reference made herein to any other International Standard implies its latest edition, unless otherwise stated. @ International Organkation for Standardkation, 1986 l Printed in Switzerland SIST EN 23823-2:2000



INTERNATIONAL STANDARD ISO 3823/2-1986 (EI Dental rotary instruments - Part 2 : Steel and carbide finishing burs 0 Introduction This International Standard is one of a series of Standards relating to dental rotary instruments. lt consists of two Parts : Part 1 : Steel and carbide burs. Part 2 : Steel and carbide finishing burs. The various dimensional and other requirements specified for steel and carbide finishing burs are those considered important to ensure the interchangeability of these instruments. Attention is drawn to ISO 6360 which specifies a 15-digit number for the identification of dental rotary instruments of all types. 3 Classification Dental 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 d, diameter of the working Part, head diameter d, neck diameter I, length of the working Part, head length lZ Overall length 1 Scope and field of application 5 Material This patt of ISO 3823 specifies dimensions of, and require- ments for, the twelve most commonly used forms of steel and carbide finishing burs. lt is envisaged to extend the scope of this International Standard to cover other forms of burs. Other characteristics of bur heads, for example spiralled blades, Cross-Cut, are not covered by this International Standard. These will be dealt with in a future International Standard. The shaft shall be made of steel or other suitable material. 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 the treatment shall be left to the discretion of the manufacturer. 6 Dimensions and number of blades All dimensions are in millimetres. 2 References I S 0 1797, Dental ro tary instrumen ts - Shanks. ISO 2157, Dental rotary instruments - Nominal sizes and designa tion. The dimensions, determined as described in ISO 3325, shall be as specified in the tables and shown in figures 1 to 12.
