31、opy, (c) BSI ISO/DIS 1112 iv ISO 2007 All rights reserved 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 committe
32、es. Each 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, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the Inte
33、rnational Electrotechnical 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 S
34、tandards 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. Attention is drawn to the possibility that some of the elements of this document may be the su
35、bject of patent rights. 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, WG3. This third edition cancels and replaces the second edition (ISO 1112:1999), which has been technically revised. Licensed Co

37、y of the timekeeping instruments comprising mobile parts. Thus the number of functional jewels of a timekeeper is a sign of quality. The watch manufacturers 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 st
38、akes led to the creation of the ISO 1112 standard, in order to specify what are horological functional jewels.
