    27、998 iv BSI 05-1999 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 su

    28、bject 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 withISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (I

    29、EC) 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 International Standard requires approval by at least75% of the member bodies casting a vote. International Stand

This second edition of ISO3823-1 contains the updated specificat

    32、ions for tungsten carbide burs. Thespecifications for steel burs remain unchanged. The various dimensional and other requirements specified for steel and carbide burs are those considered important to ensure the interchangeability and safe usage of these instruments in the practice of dentistry. The

    33、 nominal diameters of the working part listed in Table 1 to Table 22 comply with the diameters specified in ISO2157. The diameter listed in the first column (preferred diameters) should be used. Attention is drawn to ISO6360, which specifies a15-digit numbering system for the identification of denta

    34、l rotary instruments of all types. 1 Scope This part of ISO3823 specifies dimensional and other relevant requirements for the10 most commonly used shapes of steel and carbide burs, including a quality control for these instruments. 2 Normative references The following standards contain provisions wh

    35、ich, through reference in this text, constitute provisions of this part of ISO3823. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of ISO3823 are encouraged to investigate the possibility of applying
