7、n) 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 subject for which a technical committee has been established has the right to be rep
8、resented 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 (IEC) on all matters of electrotechnical standardization. International Standards a
9、re drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. 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
10、a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 4093 was prepared by Technical Committee ISO/TC 22,
11、Road vehicles, Subcommittee SC 7, Injection equipment and filters for use on road vehicles.

12、ion pumps High-pressure pipes for testing 1 Scope This International Standard specifies the functional requirements of a range of high-pressure pipes for use on benches for the testing and setting of fuel injection pumps intended for diesel engines. Only dimensions and requirements affecting the hyd
13、raulic characteristics of the pipes are specified. Other requirements, such as the type of end connections or shape of the pipes when bent, are not included as these depend on the connections provided on the pump outlets and injector inlets, and on the design features of individual pumps and test be
14、nches. This International Standard applies to a range of pipes to enable the pump engine manufacturer to choose a suitable type of pipe for pump deliveries up to 300 mm 3 /stroke/cylinder. The particular pipe to be used shall be identified by the pump manufacturer in the test schedule for each indiv
15、idual pump type and application. 2 Normative reference The following normative document contains provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, this publication do not apply. How
16、ever, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent edition of the normative document indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and I
17、EC maintain registers of currently valid International Standards.

18、tandardized high-pressure pipes for testing. If pipes of dimensions other than those specified in the table must be used for special technical reasons, the dimensions of such non-standard pipes shall be clearly specified in the pump test schedule.ISO 4093:1999(E) 2 ISO 1999 All rights reserved Table

21、y shall have a smooth internal bore, free from cracks or other structural weaknesses and from corrosion or other matter likely to cause damage to the fuel injection system. 4.2 After making the connection ends, any closing-in of the pipe shall be removed by inserting a reamer of the nominal internal
22、 diameter of the pipe to a depth at least twice that to the length of the deformed end (connection end) of the pipe. Any closing-in of the connection ends after extended use shall also be similarly removed. 4.3 The radius of any bend subsequently made in manufacturing the pipes shall be not less tha
23、n that recommended in the table measured from the centreline of the pipe. 4.4 Pipes shall be washed internally after the making of connection ends and bending, in order to remove extraneous matter. 4.5 For storage, the ends shall be closed off from ingress of air in order to avoid internal corrosion
24、. 5 Designation of high-pressure pipes Pipes should preferably be identified by a tag or clip citing the ISO designation in accordance with the table, for example.ISO 4093:1999(E) ISO 1999 All rights reserved 3 Bibliography 1 ISO 2974, Diesel engines High-pressure fuel injection pipe end-connections
