12、 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 that committee. Int
13、ernational 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 in accordance with t
14、he 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 technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval
15、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.

19、cope This part of ISO 702 specifies the sizes for interchangeability of conical spindle noses and corresponding connecting faces of face plates or work holding chucks. NOTE The “camlock type”, “bayonet type” and “cylindrical connection” are specified in ISO 702-2, ISO 702-3 and ISO 702-4, respective
20、ly. 2 Interchangeability In this part of ISO 702, all dimensions and tolerances are expressed in millimetres. Although there are differences in the values of dimensions and assembly screws in metric and inch series, the connecting dimensions in Tables 1 and 2 allow for interchangeability between met
21、ric- and inch-based chucks (see also footnote “a” in Table 2). 3 Sizes for interchangeability 3.1 Spindle noses See Figure 1 and Table 1. Type A1: Two bolt circles of diameter d 2and d 3 ; Type A2: One outer bolt circle of diameter d 3(Type A2 for Nos. 3 and 4; types A1 and A2 for Nos. 5 to 28). BS
