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 patt 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 3630/2 was prepared by Technical Committee ISO/TC 106, Dentistry. NOTE - ISO 3630/2 was originally circulated as ISO/DIS 3630/DAD 1. 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. 0 International Organkation for Standardkation, 1966 0 Printed in Switzerland SIST EN 23630-2:2000

INTERNATIONAL STANDARD ISO 3630/2-1986 (E) Dental root canal instruments - Part 2: Enlargers 0 Introduction 3 Material This part of ISO 3630 forms part of a three-part International Standard on dental root canal instruments which will eventually comprise The instruments shall be made from cold worked tool steel. The type of steel and the treatment given to it is left to the discre- tion of the manufacturer. Part 1: Files, reamers and barbed broaches. 4 Dimensional requirements Part 2: Enlargers. The dimensions are given in millimetres. Part 3: Condensers and spreaders. When the first edition of ISO 3630 (ISO 3630-1984) is revised, it will be renumbered as ISO 3630/1. Further requirements (for example bending, torque and cutting ability) will be included in future work on this three-part series of ISO 3630. The dimensional requirements of the instruments shall comply with the respective tables and figures; within the dimensional requirements, variations in shape and design are permissible. Compliance shall be tested in accordance with ISO 3630. Attention is drawn to ISO 6360 which specifies a 15-digit number for the identification of dental rotary instruments of all types. 4.1 Nominal diameters and nominal size designation Table 1 gives the series of nominal diameters for the working part and the corresponding designations to be used for the types of dental root canal instruments specified in this part of ISO 3630. 1 Scope and field of application This part of ISO 3630 specifies requirements for root canal instruments of the following types: a) enlarger, type G; b) enlarger, type BI; c) enlarger, type P. 2 References ISO 1797, Dental rotary instruments - Shaniks.
