7、ldwide 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
8、 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
9、in accordance with the rules given in the ISO/IEC Directives, Part 3. 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. Att
10、ention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 3764 was prepared by Technical Committee ISO/TC 114,Horology, S
11、ubcommittee SC 7,Overall dimensions. This third edition cancels and replaces the second edition (ISO 3764:1997), of which it constitutes a minor revision. INTERNATIONAL STANDARDISO 3764:2000(E) ISO 2000 All rights reserved1 Timekeeping instruments Movements Types, dimensions and nomenclature 1Scope
12、This International Standard specifies the types and fitting dimensions of mechanical and electromechanical watch- movements. This International Standard is applicable to the four following types of movements: ?Type 1: round; ?Type 2: shaped round; ?Type 3: 5 ?; ?Type 4: 6 ? 8?. 2Normative references
13、 The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this Int
14、ernational Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid In
15、ternational Standards. ISO 286-1,ISO system of limits and fits Part 1: Bases of tolerances, deviations and fits ISO 6426-2,Horological vocabulary Part 2: Technico-commercial definitions. 3Terms and definitions For the purposes of this International Standard, the terms and definitions given in ISO 28
16、6-1 and ISO 6426-2, and the following, apply. 3.1Diameters of movement 3.1.1 casing diameter d1 diameter of a plate, or an equivalent part or an assembly unit, by which the movement is located in the watch-case NOTEThe protruding elements of movement parts are not included in the casing diameter if
17、the protrusion does not exceed 1,5 % of a diameter value and if in length it is no more than 10 % of the plate perimeter.

20、ace NOTEIf the battery is not the most protruding part, the total movement thickness is determined as l1. 3.2.2.3 total thickness of the movement including a battery and its fastening clamp l3 distance between the dial support surface and the lower surface of the clamp NOTE 1If the battery with its
21、clamp is not the most protruding part, the total movement thickness is determined as l1. NOTE 2For watches with analog display, the total thickness of the movement does not include the projection of the hand- fastening elements nor the elements providing electrical contact with the case. 4Nomenclatu
