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 3. 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 part of ISO 10692 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 10692 consists of the following parts, under the general title Gas cylinders Gas cylinder valve connections for use in the micro-electronics industry: Part 1: Outlet connections Part 2: Specification and type testing for valve to cylinder connections Annexes A to C of this part of ISO 10692 are for information only.

These applications require that the gas be almost completely free of particles which can be generated by the fitting of a valve to a cylinder. This part of ISO 10692 specifies a prototype test programme for the valve to cylinder connection for these special applications. Whilst passing the required safety tests, existing connecting systems such as tapered threads may not necessarily pass the recommended tests for durability and other operational features. Because of the opportunity for new technical solutions, this is a performance standard rather than a document detailing a dimensioned system.

It specifies a mandatory type test programme to ensure the safety of the valve to cylinder connection. Additional tests recommended for assessment of durability and other operational features of the connection are given in annex A. 2Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO 10692.

The connection shall be capable of withstanding all situations encountered during normal transport, handling and use without loss of integrity. This includes resistance to impact damage, temperature and pressure variation and vibration. The connection shall also be capable of meeting the user's requirements concerning leak integrity and maintenance of gas purity. 1 EN ISO 106922:2001 Licensed Copy: sheffieldun sheffieldun, na, Sun Nov 19 08:40:11 GMT+00:00 2006, Uncontrolled Copy, (c) BSI ISO -296012:(1002E) 2© ISO 1002 All rights rsedevre 4Sequence for safety tests Every type of valve to cylinder connection for use in the microelectronics industry shall be prototype tested according to the sequences given below before being put into service. Any modification on material requires a new type test. This test shall be performed with a valve mounted on a gas cylinder with a water capacity of approximately 50 l and a maximum operating pressure of 200 bar. If the connection is specifically designed for use with cylinders with a smaller capacity than 50 l, a cylinder of this size shall be used. The tightness of the connection shall be tested after each step by pressurizing the cylinder with air or nitrogen at 10 bar gas pressure to check for
