The UK participation in its preparation was entrusted to Technical Committee CH/52, Dental instruments, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation
4、, or proposals for change, and keep the UKinterests informed; monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this committee can be obtained on request to its secretary. Cross-references Attention is drawn to the fact that
5、 CEN and CENELEC Standards normally include an annex which lists normative references to international publications with their corresponding European publications. The British Standards which implement international or European publications referred to in this document may be found in the BSI Standa

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
30、ard ISO3823-1 was prepared by Technical Committee ISO/TC106, Dentistry, Subcommittee SC4, Dental instruments. This second edition cancels and replaces the first edition (ISO3823-1:1986), which has been technically revised. ISO3823 consists of the following parts, under the general title Dental rotar
31、y instruments Burs: Part 1: Steel and carbide burs; Part 2: Steel and carbide finishing burs.ENISO3823-1:1998 BSI 05-1999 1 Introduction This International Standard is one of a series of standards relating to dental rotary instruments. 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
36、the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards.
