The work of preparing International Standar
7、ds is normally carried out through ISO 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
8、 part in the work. ISO collaborates closely with the International Electrotechnical 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
9、to prepare International Standards. 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 75 % of the member bodies casting a vote. Attention is drawn to the possibility
10、 that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 7299-1 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 7, Injection equipment and filters for use on roa
11、d vehicles. This first edition, together with the first edition of ISO 7299-2, cancels and replaces the second edition of ISO 7299 (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: Par
12、t 1: Fuel injection pumps Part 2: High-pressure supply pumps for common rail fuel injection systems BS ISO 7299-1:20071Diesel engines End-mounting flanges for pumps Part 1: Fuel injection pumps 1 Scope This International Standard specifies dimensional requirements for nine types of end-mounting flan
13、ges for fuel injection pumps (rotary, distributor and in-line fuel injection pumps) 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
14、. For undated 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 are encouraged to use the tolerance H8 for the female
15、register diameter. If functionally necessary, the tolerance g8 on the pump spigot diameter (d1in the figures) may be replaced by f7, and the tolerance H8 on the female register diameter may be replaced by H7, by mutual agreement between supplier and user. NOTE 1 The diameter d2 in the figures and ta
16、bles corresponds to the diameter d specified in ISO 6519. NOTE 2 The flange configuration can optionally be rotated relative to the pump housing.
