10、) ISO 2009 All rights reserved iiiForeword 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 int

11、erested in a subject 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 with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnic

12、al Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the

13、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. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

14、ISO shall not be held responsible for identifying any or all such patent rights. ISO 1112 was prepared by Technical Committee ISO/TC 114, Horology. This third edition cancels and replaces the second edition (ISO 1112:1999), which has been technically revised. BS ISO 1112:2009ISO 1112:2009(E) iv ISO

15、2009 All rights reservedIntroduction Horological functional jewels, by stabilizing friction and reducing wear, contribute to the quality and longevity of the timekeeping instruments comprising mobile parts. Thus, the number of functional jewels of a timekeeper is a sign of quality. The watch manufac

16、turers use this fact to promote their products and some watch-importing countries use it as a basis for defining custom duties. The extent of these stakes led to the creation of ISO 1112, in order to specify what are horological functional jewels. BS ISO 1112:2009INTERNATIONAL STANDARD ISO 1112:2009

17、(E) ISO 2009 All rights reserved 1Horology Functional and non-functional jewels 1 Scope This International Standard specifies the technical definitions of functional and non-functional horological movement jewels.
