The work of preparing International Standards is normally carried out through ISO technica
10、l 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 in the work. ISO collaborates closely wit
11、h 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 least75% of the
12、 member bodies casting a vote. International Standard ISO7879 was prepared by Technical Committee ISO/TC22, Road vehicles, Sub-committee SC7, Injection equipment and filters for use on road vehicles. This third edition cancels and replaces the second edition (ISO7879:1990), of which it constitutes a
