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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directives
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. Details of any
patent rights identified during the development of the document will be in the Introduction and/or on
the ISO list of patent declarations received. www.iso.org/patents
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 44, Welding and allied processes, Subcommittee
SC 8, Equipment for gas welding, cutting and allied processes.
This third edition cancels and replaces the second edition (ISO 14113:2007), of which it constitutes a
minor revision with the following changes:
— correction of temperature value in 7.5;
— editorial revision.

INTERNATIONAL STANDARD ISO 14113:2013(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 450 bar
(45 MPa), 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).

ISO 23529, Rubber — General procedures for preparing and conditioning test pieces for physical test methods
3 Terms and definitions
For the purposes of this document, the terms and definitions 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 1 to entry: 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
[SOURCE: ISO 8330:2007, definition 2.1.21]
3.3
distance 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
sub-assembly of components enabling the hose to be safely connected to other pressurized 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 to entry: 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
