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 12209 was prepared by Technical Committee ISO/TC 58, Gas cylinders, Subcommittee SC 2, Cylinder
fittings, in collaboration with Technical Committee CEN/TC 23, Transportable gas cylinders.
This first edition of ISO 12209 cancels and replaces the first editions of the ISO 12209 series
(ISO 12209-1:2000, ISO 12209-2:2000, ISO 12209-3:2000), which have been technically revised.
The main changes are:
— combination of former three parts of ISO 12209 into a single ISO 12209;
— modification of valve outlet, adaptor and o-ring dimensions; and
— addition of an outlet connection type test procedure in Annex A.

INTERNATIONAL STANDARD ISO 12209:2013(E)
Gas cylinders — Outlet connections for gas cylinder valves
for compressed breathable air
1 Scope
This International Standard specifies the characteristics of outlet connections for gas cylinder valves
for compressed breathable air gas cylinders. It states the fundamental requirements for both; the
connection and its components and includes basic dimensions. Included in this International Standard
are the following connections:
— yoke type outlet connection for SCUBA use up to a maximum cylinder working pressure of 232 bar;
— threaded type outlet connections up to a maximum cylinder working pressure of 232 bar and
300 bar; and
— threaded type outlet connection for SCUBA use up to a maximum cylinder working pressure of
232 bar including adaptor for users to convert into a yoke type outlet.
Annex A gives the outlet connection type test procedures.
Requirements for cylinder valves (see ISO 10297) are not covered by this International Standard.
Requirements for material specifications and gas/material compatibility (see ISO 11114-1 and
ISO 11114-2) are not covered by this International Standard.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
ISO 2768-1, General tolerances — Part 1: Tolerances for linear and angular dimensions without individual
tolerance indications
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
working pressure
settled pressure of a compressed gas at a uniform reference temperature of 15 °C in a full gas cylinder
[SOURCE: ISO 10286:2007, definition A.2.8]
3.2
SCUBA
self-contained underwater breathing apparatus
3.3
compressed breathable air
gas which has the nominal composition of atmospheric air and is subject to purity level controls
ISO 12209:2013(E)
4 Yoke type outlet connection for SCUBA use up to a maximum cylinder working
pressure of 232 bar
Figure 1 shows an example of the yoke type outlet connection in the assembled state.
The valve outlet and o-ring dimensions including minimum shore hardness (HS) are shown in Figure 2
and given in Table 1 and Table 2.
The exact form of the o-ring groove is the responsibility of the manufacturer providing the connection
passes the outlet connection type test according to Annex A using an o-ring specified in Table 2.
In order to ensure that the yoke does fit over the valve, minimum dimensions are given for the yoke (see
Figure 3 and Table 3).
No outer dimensions are given for the yoke. However, the dimensions shall be chosen such that the yoke
can resist a torque applied via the screw of 20 Nm without visible permanent deformation of the thread
and/or the yoke. In addition, the tests described in Annex A shall be carried out.
Unless otherwise specified, the general tolerances for linear and angular dimensions shall be in
accordance with class m of ISO 2768-1.
