Rubber hoses and hose assemblies for bulk fuel delivery by truck — Specification
ISO 2929:2002 specifies the requirements for two groups of rubber hoses and rubber hose assemblies for loading and discharge of liquid hydrocarbon fuels with a maximum working pressure of 10 bar (1,0 MPa). Both groups of hoses are designed for: use with hydrocarbon fuels having an aromatic-hydrocarbon content not exceeding 50 % by volume and containing up to 15 % of oxygenated compounds; operation within the temperature range of -30 °C to +70 °C, undamaged by climatic conditions of -50 °C to +70 °C when stored in static conditions. ISO 2929:2002 is not applicable to hoses and hose assemblies for LPG systems, aviation fuel systems, fuel station systems or marine applications.

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 3.
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 International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 2929 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee SC 1,
Hoses (rubber and plastics).
This third edition cancels and replaces the second edition (ISO 2929:1991), which has been technically revised.
Annexes A to E form a normative part of this International Standard. Annex F is for information only.

INTERNATIONAL STANDARD ISO 2929:2002(E)
Rubber hoses and hose assemblies for bulk fuel delivery by
truck — Specification
WARNING — Persons using this International Standard should be familiar with normal laboratory practice.
This standard does not purport to address all of the safety problems, if any, associated with its use. It is
the responsibility of the user to establish appropriate health and safety practices and to ensure compliance
with any national regulatory conditions.
1 Scope
This International Standard specifies the requirements for two groups of rubber hoses and rubber hose assemblies
for loading and discharge of liquid hydrocarbon fuels with a maximum working pressure of 10 bar (1,0 MPa).
Both groups of hoses are designed for:
a) use with hydrocarbon fuels having an aromatic-hydrocarbon content not exceeding 50 % by volume and
containing up to 15 % of oxygenated compounds;
b) operation within the temperature range of − 30 °C to + 70 °C, undamaged by climatic conditions of − 50 °C to
+ 70 °C when stored in static conditions.
NOTE Hoses for use at temperatures lower than − 30 °C should be the subject of discussion between manufacturer and
end user.
This International Standard is not applicable to hoses and hose assemblies for LPG systems, aviation fuel systems,
fuel station systems or marine applications.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of
this International Standard. For dated references, subsequent amendments to, or revisions of, any of these
publications do not apply. However, parties to agreements based on this International Standard are encouraged to
investigate the possibility of applying the most recent editions of the normative documents indicated below. For
undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC
maintain registers of currently valid International Standards.

3 Terms and definitions
For the purposes of this International Standard, the terms and definitions given in ISO 8330 apply.
4 Classification
Hoses are designated as belonging to one of the following groups:
a) Group D: delivery hose, or, with certain restrictions, for use in low-vacuum applications (see footnote to
Table 3).
b) Group SD: suction and delivery hose, helix-reinforced.
Both of these groups can be:
a) electrically bonded, in which case the hose is designated and marked M-grade;
or
b) electrically conductive, using a conductive rubber layer, in which case the hose is designated and marked
Ω-grade.
5 Materials and construction
If the hose is mandrel-built, particulate-type release agents shall not be used.
The hose shall be uniform in quality and free from porosity, air-holes, foreign inclusions and other defects.
The hose shall consist of the following:
a) a lining of rubber resistant to hydrocarbon fuels;
b) a reinforcement of layers of woven, braided or spirally wound textile material;
c) an embedded helix reinforcement (group SD only);
d) two or more low-resistance electrical bonding wires (M-grade only);
e) an outer cover of rubber, resistant to abrasion, outdoor exposure and hydrocarbon fuels.

6.1 Nominal bore, internal diameter, outside diameter and their tolerances, service reeling
diameter and minimum bend radius
When measured in accordance with ISO 4671, the internal diameter and outside diameter and their tolerances
shall conform to the values specified in Table 1.
When determined in accordance with ISO 1746, the value of the minimum bend radius shall conform to the values
