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 3807 was prepared by Technical Committee ISO/TC 58, Gas cylinders.
This second edition of ISO 3807 cancels and replaces the first edition of ISO 3807-1:2000 and the first
edition of ISO 3807-2:2000. The main technical modifications are the following:
a) ISO 3807-1 and ISO 3807-2 were revised taking into account EN 1800 and the according requirements
were merged into one standard (ISO 3807).
b) A test for the compressive strength of the porous material was added.
c) A calculation method as an alternative to the elevated temperature test was added.
d) The impact stability test was removed.
e) The procedure for establishing permissible acetylene/solvent concentrations for bundles was
removed and is now included in ISO 13088.

Introduction
There are two types of acetylene cylinders operated in certain parts of the world:
— acetylene cylinders with a test pressure of at least 60 bar and without fusible plugs;
— acetylene cylinders with a test pressure of at least 52 bar, fitted with fusible plugs which release the
gas and hence reduce the pressure if the cylinder temperature increases unintentionally.
This International Standard covers the requirements for both types of acetylene cylinders and specifies
specific requirements in separate Annexes.
This International Standard is intended to be used under a variety of national regulatory regimes but has
[1]
been written so that it is suitable for the application of the UN Model Regulations . Attention is drawn to
requirements in the specified relevant national regulations of the country (countries) where the cylinders
are intended to be used that might override the requirements given in this International Standard.
In International Standards, weight is equivalent to a force, expressed in Newton. However, in common
parlance (as used in terms defined in this International Standard), the word “weight” continues to be
used to mean “mass”, even though this practice is deprecated (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 according SI unit for pressure is Pa.
Pressure values given in this International Standard are given as gauge pressure (pressure exceeding
atmospheric pressure) unless noted otherwise.

INTERNATIONAL STANDARD ISO 3807:2013(E)
Gas cylinders — Acetylene cylinders — Basic requirements
and type testing
1 Scope
This International Standard specifies the basic and type testing requirements for acetylene cylinders with
and without fusible plugs with a maximum nominal water capacity of 150 l and requirements regarding
production/batch test procedures for manufacturing of acetylene cylinders with porous material.
It does not include details of the design of the cylinder shell; these are specified, for example, in
ISO 9809-1, ISO 9809-3, ISO 4706 and ISO 7866.
NOTE The limitation to 150 l is derived from the definition for cylinder in the UN Model Regulations. However,
in practice acetylene cylinders in general have lower water capacities than 150 l.

4 Basic requirements
4.1 Cylinder shell
The acetylene cylinder shell shall conform to the requirements of the relevant International Standard
for design and construction of the cylinders, e.g.
— for seamless steel, ISO 9809-1, ISO 9809-3;
— for welded steel, ISO 4706;
— for seamless aluminium alloy, ISO 7866.
NOTE Other standards for the design and construction of cylinders are in preparation and appropriate
standards should be conformed to when published.
The minimum test pressure for acetylene cylinders without fusible plugs shall be 60 bar.
The minimum test pressure for acetylene cylinders with fusible plugs shall be 52 bar.
4.2 Porous material
The porous material shall be compatible with the cylinder shell, the solvent and acetylene and shall
not form dangerous or harmful products with these. For common porous materials consisting of inert
materials (e.g. calcium silicate hydrate), this is generally the case.
The maximum specified porosity shall not exceed the minimum specified porosity by more than 3 %
when determined in accordance with Annex A.
P − P ≤ 3 %

---------------------- Page: 15 ----------------------
SIST EN ISO 3807:2013
ISO 3807:2013(E)
The compressive strength as determined in accordance with Annex B shall be at least 2 MPa (20 bar).
For safety reasons, the porous material shall be able to prevent the propagation of an acetylene
decomposition within the cylinder and shall be of such quality that it enables the acetylene cylinder to
meet the requirements of Annex D and Annex E.
Acetylene cylinders equipped with fusible plugs shall pass the fire test described in Annex F in addition.
Where cylinder shells with joggle welds are used, it shall be verified that the welds do not damage the
porous material in accordance with Annex G.
To ensure the quality and uniform distribution of the porous material in the acetylene cylinder and
the quality and amount of the solvent, test procedures shall be established by the manufacturer of the
porous material in accordance with Annex I.
4.3 Solvent content and acetylene content
The solvent shall be compatible with the cylinder shell. For the commonly used solvents acetone and
DMF this is generally the case.
The specified solvent content and the maximum acetylene content for an acetylene cylinder shall be
such that the cylinder will meet the requirements specified in Annex D and Annex E.
The specified solvent content and the maximum acetylene content for an acetylene cylinder equipped with
fusible plugs shall be such that the cylinder will meet the requirements specified in Annex F in addition.
4.4 Working pressure
When the cylinder has been filled with the specified solvent content and the maximum acetylene content,
and the pressure has reached equilibrium at a uniform reference temperature of 15 °C, the gauge pressure
in the cylinder shall not exceed the working pressure as calculated in accordance with Annex C.
4.5 Cylinder identification
For the stamp marking of acetylene cylinders see the relevant regulations. Further information can be
found in ISO 13769.
In addition, solvent free acetylene cylinders shall bear the words “solvent-free” painted in a clear and
visible manner.
NOTE Attention is drawn to requirements for marking in relevant regulations that might override the
requirements given in this International Standard.
4.6 Fusible plugs
For acetylene cylinders equipped with fusible plugs, the fusible plugs shall be sized and selected as to
location and quantity so that the fusible plug(s) are capable of preventing bursting of the normally filled
cylinder when subjected to a fire test in accordance with Annex F.
The fusible plug shall utilize a fusible alloy having a yield temperature between 98 °C and 110 °C. The
yield temperature is the temperature at which the fusible alloy becomes sufficiently soft to extrude
from its holder to permit discharge of acetylene.
The fusible alloy may be installed in a threaded steel or brass plug. The threaded plug shall be fitted into
a boss or pad, preferably on the cylinder top or in the cylinder valve. Bottom plugs are not permitted for
cylinders used in bundles.
The fusible plugs shall be sample tested for yield temperature and for resistance to extrusion and
leakage as a quality control procedure during manufacture and prior to installation into the cylinder in
accordance with Annex H.
