The work of preparing International Standards is normally carried out through ISO technical committees. Each member
9、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 in the work. ISO collaborates closely with the International Electr
10、otechnical Commission (IEC) on all matters of electrotechnical standardization. International 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 Standards adopted
11、 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
12、rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 11565 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 1, Ignition equipment. This second edition cancels and replaces the first edition (ISO 11565:1998), which has been technica
13、lly revised.
