Small medical gas cylinders - Pin-index yoke-type valve connections (ISO 407:2004)
ISO 407:2004 concerns pin-index yoke-type valve connections for small medical gas cylinders, with a maximum working pressure (filling pressure at 15 °C) of 200 bar. This type of connection is typically used for small cylinders (5 l or below). In some cases, it may be used for larger cylinders. In this latter case, consideration shall be given to the need for valve protection.
It specifies:
basic dimensions;
requirements for alternative designs of the yoke-type valve connections;
dimensions and positions for the holes and pins for the outlet connections.
It also specifies the dimensions and positions for the holes and pins for the outlet connections for certain gases and gas mixtures.
ISO 407:2004 applies to small medical gas cylinders used for patient care, including therapeutic, diagnostic and prophylactic applications, in hospitals and for emergency treatment.

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 407 was prepared by Technical Committee ISO/TC 58, Gas cylinders, Subcommittee SC 2, Cylinder
fittings.
This third edition cancels and replaces the second edition (ISO 407:1991), which has been technically revised.

INTERNATIONAL STANDARD ISO 407:2004(E)
Small medical gas cylinders — Pin-index yoke-type valve
connections
1 Scope
This International Standard concerns pin-index yoke-type valve connections for small medical gas cylinders,
with a maximum working pressure (filling pressure at 15 °C) of 200 bar. This type of connection is typically
used for small cylinders (5 l or below). In some cases, it may be used for larger cylinders. In this latter case,
consideration shall be given to the need for valve protection.
It specifies:
basic dimensions;
requirements for alternative designs of the yoke-type valve connections;
dimensions and positions for the holes and pins for the outlet connections.
It also specifies the dimensions and positions for the holes and pins for the outlet connections for the gases
and gas mixtures given in Table 1.
This International Standard applies to small medical gas cylinders used for patient care, including therapeutic,
diagnostic and prophylactic applications, in hospitals and for emergency treatment.
2 Normative references

3 Valve
Each small medical gas cylinder can be fitted with a yoke valve (see Clause 5). The yoke valve shall have
location holes of the dimensions and in the positions indicated in Clause 7 for the appropriate gas or gas
mixture.
The name or chemical symbol of the gas or gas mixture shall be clearly and indelibly stamped on the valve.

4 Yoke
The connecting yoke shall conform to the requirements and dimensions given in Clauses 5 and 6. The yoke
shall be fitted with pins, the dimensions and the positions of which correspond to the holes in the valve as
indicated in Clause 7 for the appropriate gas or gas mixture.
The name or chemical symbol of the gas or gas mixture shall be clearly and indelibly stamped on the yoke. If
an identification colour is used, it shall be in conformity with ISO 32.
Examples of the alternative designs for the connecting yoke are given in 6.2.
