The work of prep
8、aring 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 that committee. International organizations, governmental and non-governmental, in
9、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 in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of
10、 technical committees is to prepare International Standards. 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
11、drawn to the possibility that some of the elements of this document may be the subject of patent rights.

12、12ISO 13074:2012(E)IntroductionThe annual world trade of clocks represents hundreds of millions of units. Clock design, trade and after-sale service are complicated by the lack of standards in many areas. One of them is the fitting dimensions of movements to hands.As there are no coherent standards
13、to be referred to, unlimited numbers of fitting dimensions are used by the producers, increasing the stocks and the production costs of movements and hands. This also causes unnecessary problems between suppliers and purchasers because of the large numbers of available adjustments.A standard dedicat
14、ed to the fitting dimensions of movements to hands will significantly minimize the number of pieces and improve interchangeability. The aim is also to increase productivity, reduce production costs and reduce stocks, thus facilitating the global trade of quartz clocks.iv ISO 2012 All rights reserved
15、BS ISO 13074:2012Analogue quartz clocks Fitting dimensions of movements to hands1 ScopeThis International Standard specifies the fitting dimensions of movements to hands. It is applicable to analogue quartz table and wall clock movements, with and without alarm, that have the following properties: m
16、inute wheel shafts with an outer diameter of between 1,3 mm and 3,6 mm; hour wheel, minute wheel, second wheel and alarm wheel shafts made of metal and plastic material. This International Standard can be referenced for other types of analogue quartz clock movements.2 Normative referencesThe followi
17、ng referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

When the shaft is cone-shaped, the dimension d indicates the top end of the shaft.NOTE 2 In many kinds of movements, the minute wheel shaft and mi
