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 14113 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee
SC 8, Equipment for gas welding, cutting and allied processes.
This second edition cancels and replaces the first edition (ISO 14113:1997), which has been technically
revised.
Requests for official interpretations of any aspect of this International Standard should be directed to the
Secretariat of ISO/TC 44/SC 8 via your national standards body, a complete listing of which can be found at

INTERNATIONAL STANDARD ISO 14113:2007(E)
Gas welding equipment — Rubber and plastics hose and hose
assemblies for use with industrial gases up to 450 bar (45 MPa)
1 Scope
This International Standard specifies requirements for rubber and plastics hose and hose assemblies for use
with compressed, liquefied and dissolved gases up to a maximum working pressure of 45 MPa (450 bar),
within the ambient temperature range of −20 °C to +60 °C.
This International Standard applies to hose assemblies used to connect industrial gas cylinders to manifolds
or bundles prior to any pressure reduction stage.
This International Standard does not cover rubber or thermoplastic hoses for welding, cutting and allied
processes (see ISO 3821 and ISO 12170).
This International Standard does not apply to refrigerated liquefied gases or to liquefied petroleum gases
(LPG).

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 15296 and the following apply.
3.1
autogenous ignition temperature
temperature at which ignition of a sample occurs when subjected to oxygen pressure and heating, and in the
absence of a source of ignition other than the applied temperature
NOTE The autogenous ignition temperature depends on the sample preparation, test apparatus and test procedure
employed.
3.2
burst pressure
pressure at which rupture of the hose occurs when tested to the relevant standard
[ISO 8330:2007, 2.1.21]
3.3
distant piece
length of metallic tubing at the end of a hose or hose assembly that serves to contain and cool the highest
temperature gas that is formed by the effect of adiabatic compression, e.g. by the rapid opening of a cylinder
valve
3.4
end fitting
subassembly of components enabling the hose to be safely connected to other pressurised equipment
3.5
hose assembly
length of hose with suitably attached end fittings
3.6
maximum working pressure
pressure to which a hose is designed to be subjected during service, including expected momentary surges
NOTE 1 This definition is consistent with that for a gas cylinder in ISO 10286:2007, A.2.4 maximum permissible
operating pressure (the highest pressure permitted to be developed during service). ISO 10286:2007 defines “working
pressure” as the “settled pressure . at a uniform . temperature of 15 °C in a full gas cylinder”.
NOTE 2 Due to the peculiar characteristics of the acetylene cylinder, there is no clearly defined maximum working
pressure for acetylene service. Applicable requirements for acetylene service are given in relevant clauses.

3.7
proof pressure
pressure applied during a non-destructive test and held for a specified period of time to prove the integrity of
the construction
NOTE It is expressed in bars.
[ISO 8330:2007, 2.1.104]
4 Construction
4.1 Hose
The hose should consist of
either:
⎯ a rubber or plastics lining,
⎯ reinforcement consisting of one or more layers, and
⎯ an outer protective cover of permeable material or perforated rubber or plastics,
for flammable gas service, the hose shall also incorporate bonding wires to provide the electrical conductivity,
see 7.8;
or:
⎯ a rubber or plastics lining, and
⎯ reinforcement consisting of one or more layers of stainless steel wire braid and/or other corrosion and
abrasion resistant material which is also designed to act as an outer protective cover and provide
electrical conductivity, see 7.8.
4.2 End fittings
Fittings shall be of permanent, swage or crimp design.
The fitting design shall enable the hose assembly to attain its burst pressure without fitting pullout or
separation from the hose.
End fittings shall be manufactured from materials that are compatible with the gases and the environment to
which they will be subjected, e.g. according to ISO 9539.
4.3 Hose assemblies
Assemblies shall consist of a length of hose and permanently attached end fittings. Field-attachable or
reusable-type fittings shall not be used. Distant pieces, when used as heat sinks as part of hose assemblies
for oxygen service (see 7.1.3) shall not be readily detachable by the user.
For maximum working pressures in excess of 40 bar (4 MPa), hoses assembled should be provided with a
suitable restraining cable or device, properly fitted to an anchor point to restrain the hose in the event of
a hose assembly failure.
