The work of preparing International Standards is
5、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, in liaison with ISO, also take part
6、in the work. ISO 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 bodies for voting. Publication as an International Standar
7、d requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 13417 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee SC 15, Airframe bearings.
