The work of preparing International Standards is normally carried out through IsO technical committees. Each member body interested in a subject for which atechnicalcommitteehas beenestablishedhasthe righttoberepresented on that committee. International organizations, governmental and non- 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. 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. International Standard ISO 2020-1 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee SC 12, Mechanical systemparts. This first edition of isO 2020-1 together with isO 2020-2 cancels and replaces IsO 2020:1984.
