9、n of 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.
10、 International 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 wi
11、th the rules given in the ISO/IEC Directives, Part 3. 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 appro
12、val by at least 75 % of the member bodies casting a vote. ISO 14278 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee SC 4, Aerospace fastener systems.

18、ONAL STANDARD ISO 14278:2002(E) ISO 2002 All rights reserved 1 Aerospace Gauges, for internal offset cruciform ribbed or unribbed drives Metric series 1 Scope This International Standard specifies the dimensions of metric gauges which check internal offset cruciform drives, ribbed or unribbed, used
19、in metric screws in the nominal thread diameter range of 1,6 mm to 20 mm. The internal offset cruciform drives, ribbed drives and unribbed, respectively are defined in ISO 14275 and ISO 14276. 2 Configuration and dimensions See Figures 1, 2 and 3 and Tables 1 and 2. Dimensions and tolerances are exp
20、ressed in millimetres. The presentation of surface-profile, perpendicularity, location and run-out tolerances conforms to ISO 1101. 3 Designation The GO and NOT GO gauge designation shall be as follows: The component part designation shall be as follows: The drive penetration gauge assembly (see Fig
21、ure 3) shall be identified by the gauge body designation.
