ISO 19013-1:2005

Rubber hoses and tubing for fuel circuits for internal combustion engines — Specification — Part 1: Diesel fuels

ISO 19013-1:2005 specifies the requirements for rubber tubing and hoses used in diesel fuel circuits for internal combustion engines. The diesel fuels covered include 'bio-diesels' which consist of the methyl ester of rape seed oil at levels up to 20 % by volume in conventional diesel fuels. In addition, this specification may also be applied as a classification system to enable original equipment manufacturers (OEMs) to detail a 'line call-out' of tests for specific applications where these are not covered by the main types specified. In this case, the hose or tubing would not carry any marking showing the number of this part of ISO 19013 but may detail the OEM's own identification markings as shown on their part drawings.

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 19013-1 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee
SC 1, Hoses (rubber and plastics).
Together with Part 2 (see below), this part of ISO 19013 cancels and replaces ISO 4639-1:1987,
ISO 4639-2:1995 and ISO 4639-3:1995, which have been technically revised.
ISO 19013 consists of the following parts, under the general title Rubber hoses and tubing for fuel circuits for
internal combustion engines — Specification:

WARNING — Persons using this part of ISO 19013 should be familiar with normal laboratory practice.
This part of ISO 19013 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 safety and health practices and to

1 Scope
This part of ISO 19013 specifies the requirements for rubber tubing and hoses used in diesel fuel circuits for
internal combustion engines. The diesel fuels covered include “bio-diesels” which consist of the methyl ester
of rape seed oil at levels up to 20 % by volume in conventional diesel fuels. In addition, this specification may
also be applied as a classification system to enable original equipment manufacturers (OEMs) to detail a
“line call-out” of tests for specific applications where these are not covered by the main types specified
(see example in Annex E). In this case, the hose or tubing would not carry any marking showing the number
of this part of ISO 19013 but may detail the OEM's own identification markings as shown on their part
drawings.

3 Classification
The product shall consist of extruded rubber materials with or without an integral reinforcement which may or
may not be pre-formed before final vulcanization. The product may also have a rubber or thermoplastic barrier
layer, either as an internal layer or forming the inner liner, to impart improved fluid resistance and/or reduced
fuel vapour permeability.
Seven hoses and tubings for specific applications are specified, as follows:
Type 1 Class A = Pressurized [7 bar (0,7 MPa) working pressure] feed and return lines from the fuel tank to
the engine compartment (−40 °C to +80 °C continuous)
Class B = Pressurized [2 bar (0,2 MPa) working pressure] feed and return lines from the fuel tank to
the engine compartment (−40 °C to +80 °C continuous)
Type 2 Class A = Pressurized [7 bar (0,7 MPa) working pressure] feed and return lines in the engine
compartment (−40 °C to +100 °C continuous)
Class B = Pressurized [2 bar (0,2 MPa) working pressure] feed and return lines in the engine
compartment (−40 °C to +100 °C continuous)
Type 3 Class A = Pressurized [7 bar (0,7 MPa) working pressure] feed and return lines in the engine
compartment (−40 °C to +125 °C continuous)
Class B = Pressurized [2 bar (0,2 MPa) working pressure] feed and return lines in the engine
compartment (−40 °C to +125 °C continuous)
Type 4 Low pressure [1,2 bar (0,12 MPa) working pressure] fuel filler, vent and vapour handling

5 Performance requirements for hose and tubing
Tests shall be selected from the following list for each application of hose or tubing, based on the performance
requirements for the finished product. Type approval tests (as defined in Clause 7) for each hose or tubing
group are given in Annex F.
a) Burst pressure: When determined in accordance with ISO 1402, the minimum burst pressure for
Types 1, 2 and 3, Class A, shall be 30 bar gauge (3,0 MPa) and for Class B shall be 12 bar gauge
(1,2 MPa). Type 4 shall be 5 bar gauge (0,5 MPa). Additionally, after fuel resistance testing [test m)],
hoses and tubing shall not have a burst pressure of less than 75 % of the original burst pressure.
b) Adhesion (for all constructions with two or more bonded layers only): When determined by the
appropriate procedure in ISO 8033, the adhesion between each pair of bonded layers shall not be less
than 1,5 kN/m.
c) Low-temperature flexibility: When tested in accordance with ISO 4672:1997, procedure B, a length of
hose or tubing which has been previously kept filled with ISO 1817 liquid C for 72 h ± 2 h at 21 °C ± 2 °C
and then kept cooled at −40 °C ± 2 °C for 72 h ± 2 h shall not exhibit any cracking when examined under
