The work of p

14、reparing 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,

15、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, Part 3. The main ta

16、sk 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 a vote. ISO 142

17、81 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee SC 4, Aerospace fastener systems.

18、is claimed that compliance with this International Standard may involve the use of a patent concerning gauges specified in this International Standard. Patent rights are held by the Phillips Screw Company worldwide. ISO takes no position concerning the evidence, validity and scope of this patent rig

19、ht. The holder of this patent right has assured the ISO that he is willing to negotiate licences under reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this respect, the statement of the holder of this patent right is registered with the ISO. Informatio

20、n may be obtained from: Phillips Screw Company 508 Edgewater Drive Wakefield, MA 01880 USA Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights other than those identified above. ISO shall not be held responsible for ident

21、ifying any or all such patent rights.

22、ernal 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 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
