9、). 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. International organizations, governmental and no
10、n-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 the rules given in the ISO/IEC Directives, Par
11、t 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 approval by at least 75 % of the member bodies casting
12、 a vote. ISO 14281 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee SC 4, Aerospace fastener systems.

18、r internal cruciform ribbed or unribbed drives Metric series 1 Scope This International Standard specifies the dimensions of metric gauges which check internal cruciform drives, ribbed or unribbed, used in metric screws in the nominal thread diameter range of 1,6 mm to 20 mm. The internal cruciform
19、drives, ribbed and unribbed, are defined respectively in ISO 12256 and ISO 14279. 2 Configuration and dimensions See Figures 1, 2 and 3 and Tables 1 and 2. Dimensions and tolerances are expressed in millimetres. The presentation of perpendicularity, location and run-out tolerances conforms to ISO 11
20、01. 3 Designation Component part designation shall be as follows: The drive penetration gauge assembly (Figure 3) shall be identified by the gauge body designation.
