ISO 2974:2005

Diesel engines — High-pressure fuel injection pipe end-connections with 60 degrees female cone

ISO 2974:2005 specifies the dimensional requirements of high-pressure pipe end-connections for diesel (compression-ignition) engine fuel injection equipment. It is applicable to externally threaded end-connections of types 1 and 2 having a 60° female cone, as well as to the pipe end assemblies of high-pressure fuel injection pipes with outside diameters of up to and including 12 mm.

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 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 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 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 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 2974 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 7, Injection
equipment and filters for use on road vehicles.
This sixth edition cancels and replaces the fifth edition (ISO 2974:2000), Table 1 of which has been technically
revised (addition of tube outside diameter of 7 mm).
