12、1 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS ISO 7612:1994 ii BSI 11-1998 Foreword ISO (the International Organization for Standardization) is a wordwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO
13、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 in the work. ISO collaborates clo
14、sely 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 7
15、5 % of the member bodies casting a vote. International Standard ISO 7612 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 7, Injection equipment and filters for use on road vehicles. This second edition cancels and replaces the first edition (ISO 7612:1983), to which hav
16、e been added 10 and 12 cylinder pump dimensions in Figure 1 and type 4 pumps (see Figure 4). Annex A of this International Standard is for information only.
