11、ghts reserved iii Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a sub
12、ject 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 Electrotechnical Commission (I
13、EC) 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 by the technical commit
14、tees 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 rights. ISO shall not be
15、 held responsible for identifying any or all such patent rights. ISO 7299-2 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 7, Injection equipment and filters for use on road vehicles. This first edition of ISO 7299-2, together with ISO 7299-1:2007, cancels and replaces
16、 ISO 7299:1996, which has been technically revised. ISO 7299 consists of the following parts, under the general title Diesel engines End-mounting flanges for pumps: Part 1: Fuel injection pumps Part 2: High-pressure supply pumps for common rail fuel injection systems BS ISO 7299-2:2009BS ISO 7299-2:

18、es of high- pressure supply pumps for common rail fuel injection systems for use in diesel (compression-ignition) engines. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undat
19、ed references, the latest edition of the referenced document (including any amendments) applies. ISO 6519, Diesel engines Fuel injection pumps Tapers for shaft ends and hubs 3 Dimensions and tolerances 3.1 General Engine manufacturers should use the tolerance H7 for the female register diameter. In
20、the figures and tables, except for Figures 2 and 5 and Tables 2 and 5 (shaft end with tang drive), the diameter d 2corresponds to the diameter d specified in ISO 6519.
