ISO 12209:2013 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 ISO 12209:2013 the following connections:
a) yoke type outlet connection for SCUBA use up to a maximum cylinder working pressure of 232 bar;
b) threaded type outlet connections up to a maximum cylinder working pressure of 232 bar and 300 bar; and
c) 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 ISO 12209:2013.
Requirements for material specifications and gas/material compatibility (see ISO 11114‑1 and ISO 11114‑2) are not covered by ISO 12209:2013.

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.

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.
