6、ganization for Standardization) is a worldwide federation of national standards bodies(ISO member bodies). The work of preparing International Standards is normally carried out through ISOtechnical committees. Each member body interested in a subject for which a technical committee has beenestablish
7、ed has the right to be represented on that committee. International organizations, governmental andnon-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the InternationalElectrotechnical Commission (IEC) on all matters of electrotechnical standardization.In
8、ternational Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standardsadopted by the technical committees are circulated to the member bodies for voting. Publica

10、.ISO 17612 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture andforestry, Subcommittee SC 4, Tractors.BS ISO 17612:2004ivIntroductionThis International Standard specifies an electrical connector for the transmission of auxiliary power within theoperator station of
11、 enclosed agricultural machines. The specification thus established will allow manufacturersto provide both individual and multiple outlets in the cab. Typical applications include monitors, light-dutycontrollers, remote operating devices and miscellaneous off-the-shelf items. Only the application d
