14、l standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical com- mittees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. Internati
15、onal organizations, governmental and non-governmental, in liai- son 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 in accordance with the r
16、ules 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. Attention is drawn to the p
17、ossibility 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.

19、ned by means of a set of fixing pins and tubes. This International Standard is applicable to wristwatch-cases with four or with two lugs. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Sta

However, parties to agreements based on this International Standard are encouraged to investi- gate the possibility of applying the most recent editions of the normative documents indica
21、ted below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain reg- isters of currently valid International Standards.

A bracelet is fastened between these lugs by the use of a fixing pin and tube. Type 2: a case with one single lug at and one at (see Figure 2). A bracelet is fastened by the use
26、of a fixing pin and tube. 5 Forms of fastening elements See Figures 1 and 2.
