Each member body interested in a subject for which a technical committee has been non-governmental, in liaison with IsO, also take part in the work. IsO collaborates closely with the InternationalElectrotechnicalCommission(lEC)onallmattersofelectrotechnicalstandardization. International Standards are drafted in accordance with the rules given in the ISO/lEC 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 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. IsO shall not be held responsible for identifying any or all such patent rights. ISO 3193 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee SC 4 Aerospacefastenersystems.

Dimensions and tolerances are expressed in millimetres. They are applicable after any coating (tolerance on shank diameter before coating is also specified for heat cured matrix coatings), but before the application of any lubricant. Details of form not stated are left to the manufacturer's discretion. Tolerances of form and position shall be as specified in IsO 7913 if not otherwise stated on product standard. @ Is0 2008 - All rights reserved 7 ISO3193:2008(E) Dimensions in millimetres Break sharp edges 0,1 to 0,4 (7) 20. 10.
