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 11372 was prepared by Technical Committee ISO/TC 58, Gas cylinders, Subcommittee SC 4,
Operational requirements for gas cylinders.
This third edition cancels and replaces the second edition (ISO 11372:2005), with the following main technical
revisions:
a) ISO 11372:2005 was revised taking into account EN 12754 and EN 1801.
b) The clauses concerning filling inspection were restructured in order to better reflect the actual proceeding
of the filling inspection.
c) A new subclause 3.3 with requirements and information regarding the solvent content was added.
d) A new Clause 4 concerning the specific filling inspection of solvent-free acetylene cylinders was added.
e) A new informative Annex A introducing the Safe operating diagram was added in order to improve the
understanding of the importance of correct filling conditions for acetylene cylinders.
f) A new normative Annex B outlining the calculations necessary for determination of the solvent content
was added.

Introduction
This International Standard aims at the harmonization of the different operating and filling conditions of
individual acetylene cylinders and covers requirements that reflect current practice and experience regarding
the inspection at the time of filling.
ISO 11372 is intended to be used under a variety of national regulatory regimes but has been written so that it
[1]
is suitable for the application of the UN Model Regulations .
Where there is any conflict between this International Standard and any applicable regulation, the regulation
always takes precedence.
In International Standards, weight is equivalent to a force, expressed in newtons. However, in common
parlance (as used in terms defined in this International Standard), the word “weight” continues to be used to
mean “mass”, but this practice is deprecated (see ISO 80000-4).
In this International Standard the unit bar is used, due to its universal use in the field of technical gases. It
should, however, be noted that bar is not an SI unit, and that the corresponding SI unit for pressure is
pascals (Pa).
Pressure values given in this International Standard are given as gauge pressure (pressure exceeding
atmospheric pressure) unless noted otherwise.
INTERNATIONAL STANDARD ISO 11372:2011(E)
Gas cylinders — Acetylene cylinders — Filling conditions and
filling inspection
1 Scope
This International Standard specifies minimum requirements for the filling conditions and filling inspection of
acetylene cylinders.
This International Standard is not applicable to an assembly of cylinders connected by a manifold, e.g.
bundles (see ISO 13088).
2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
2.1
acetylene cylinder
cylinder manufactured and suitable for the transport of acetylene, containing a porous material and solvent
(where applicable) for acetylene, with a valve and other accessories affixed to the cylinder
NOTE 1 For solvent-free acetylene cylinders, see Clause 4.
NOTE 2 When there is no risk of ambiguity, the word “cylinder” is used.
2.2
cylinder shell
acetylene cylinders empty cylinder manufactured and suitable for receiving and containing a porous material
for use as part of an acetylene cylinder
2.3
filler
gas cylinders trained person responsible for inspection prior to, during and immediately after filling
2.4
maximum acetylene content
acetylene cylinders specified maximum weight of acetylene including saturation acetylene in the cylinder
2.5
maximum acetylene charge
acetylene cylinders maximum acetylene content minus the saturation gas
2.6
porous material
acetylene cylinders single- or multiple-component material introduced to or formed in the cylinder shell that,
due to its porosity, allows the absorption of a solvent/acetylene solution
NOTE The porous material may be either:
monolithic, consisting of a solid product obtained by reacting materials or by materials connected together with a
binder, or
non-monolithic, consisting of granular, fibrous or similar materials without the addition of a binder.
ISO 11372:2011(E)
2.7
residual gas
acetylene cylinders weight of acetylene including the saturation acetylene, contained in a cylinder returned
for filling
2.8
saturation gas
acetylene cylinders acetylene that remains dissolved in the solvent in the cylinder at atmospheric pressure
(1,013 bar) and at a temperature of 15 °C
2.9
solvent
acetylene cylinders liquid that is absorbed by the porous material and is capable of dissolving and releasing
acetylene
NOTE The following abbreviations are used:
“A” for acetone;
“DMF” for dimethylformamide.
2.10
specified solvent content
