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.
ISO 13296 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 13296:1997), which has been technically
revised. It also incorporates the Technical Corrigendum ISO 13296:1997/Cor.1:2000.

Introduction
The International Organization for Standardization (ISO) draws attention to the fact that it is claimed that
compliance with this International Standard may involve the use of a patent concerning an apparatus to
measure the inside diameter of the pipe assembly, as described in Annex B.
ISO takes no position concerning the evidence, validity and scope of this patent right.
The holder of this patent right has assured ISO that he is willing to negotiate licenses under reasonable and
non-discriminatory terms and conditions with applicants throughout the world. In this respect, the statement of
the holder of this patent right is registered with ISO. Information may be obtained from:
DaimlerChrysler AG
70322 Stuttgart
Germany
This information is given for the convenience of the users of this International Standard and does not
constitute an endorsement of the apparatus for which a patent is held by the above-mentioned company.
Other apparatus may be used if it can be shown to lead to the same results.
Attention is drawn to the possibility that some of the elements of this International Standard may be the
subject of patent rights other than those identified above. ISO shall not be held responsible for identifying any
or all such patent rights.

INTERNATIONAL STANDARD ISO 13296:2005(E)
Diesel engines — High-pressure fuel injection pipe
assemblies — General requirements and dimensions
1 Scope
This International Standard specifies dimensions and requirements for high-pressure fuel injection pipe
assemblies and assembled pipe sets used on diesel (compression-ignition) engines.
NOTE High-pressure pipes for use on test benches are specified in ISO 4093.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO 2974, Diesel engines — High-pressure fuel injection pipe end-connections with 60° female cone
ISO 7876-4, Fuel injection equipment — Vocabulary — Part 4: High-pressure pipes and end-connections
ISO 8535-1, Compression-ignition engines — Steel tubes for high-pressure fuel injection pipes — Part 1:
Requirements for seamless cold-drawn single-wall tubes
ISO 8535-2, Compression-ignition engines — Steel tubes for high-pressure fuel injection pipes — Part 2:
Requirements for composite tubes
ISO 12345, Diesel engines — Cleanliness assessment of fuel injection equipment
3 Definitions
For the purposes of this document, the definitions given in ISO 7876-4 apply.
4 Dimensions and tolerances
The requirement and configuration drawing for a pipe assembly shall include at least the following:
a) indication of compliance with this International Standard;
b) the outside diameter and inside diameter of the pipe and indication of compliance with ISO 8535-1 or
ISO 8535-2; and
c) a graphic representation of the centreline of the pipe with the connection ends and each bend intersection
labelled as a point, with each point listed in a table with Cartesian coordinates x, y and z with the
orthogonal distance from the axis and the bend radius;
NOTE The coordinates are used to specify the theoretical exact centreline of the pipe. See the example given in
Figure 1.

d) the developed length of the pipe as an approximated value; and
e) the surface finish requirements of the pipe and connector nuts.
The dimensional tolerance of a pipe assembly shall be stated in terms of the actual outside contour of the tube
in relation to the specified maximum outside contour and the variance of the actual connection end from
specified position, as agreed upon between supplier and customer.

5 Cleanliness
The bore of a high-pressure fuel injection pipe assembly shall be clean, and this shall be assessed in
accordance with ISO 12345. Unless otherwise agreed between manufacturer and client, cleanliness of pipe
assemblies shall be designated using the Fuel Injection Equipment Cleanliness Code (FIECC), as defined in
ISO 12345.
