4、odies) The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be re- presented on that committee. International organizations, governmental
5、and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member
6、bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard IS0 3186 was prepared by Technical Committee lSO/TC 20, Aircraft and space vehicles, Subcommittee SC 4, Aerospace fastener systems. 0 IS0 1994 Al

10、dimensions of large bihexagonal head bolts, with close or large tolerance normal shank, and short or medium length MJ threads, in metallic material, coated or uncoated, with strength classes 1 250 MPa to 1 800 MPa. It is intended for the drawing up of aerospace product standards. 2 Normative referen
