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.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

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. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following

URL: www .iso .org/ iso/ foreword .html.

This document was prepared by Technical Committee ISO/TC 58, Gas cylinders, Subcommittee SC 2,

Cylinders fittings.

This fourth edition cancels and replaces the third edition (ISO 407:2004), which has been technically

revised.
The main changes compared to the previous edition are as follows:

— addition of a note in Figure 1 on the introduction of a radius to avoid stress concentration;

— addition of dimension "m" in Figure 1;

— the basic dimensions for pin index yoke type value connections have been revised (see Table 2);

— addition of a requirement for the design of the connecting yoke.

Any feedback or questions on this document should be directed to the user’s national standards body. A

complete listing of these bodies can be found at www .iso .org/ members .html.

Small medical gas cylinders — Pin-index yoke-type valve
connections
1 Scope

This document concerns pin-index yoke-type valve connections for medical gas cylinders, with a

working pressure up to a maximum of 200 bar and/or test pressure up to a maximum of 300 bar.

NOTE This type of connection is primarily used for small cylinders (5 l or below).

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.

4 Valve

Each small medical gas cylinder can be fitted with a yoke valve (see Clause 6). The yoke valve shall have

location holes of the dimensions and in the positions indicated in Clause 8 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.
