It is the UK implementation of ISO 213582007. The UK participation in its preparation was entrusted to Technical Committee MCE/8, Compressors, pneumatic tools, pneumatic machines and vacuum technology. A list of organizations represented on this committee can be obtained on request to its secretary. This publication does not purport to include all the necessary provisions of a contract.

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 21358 was prepared by Technical Committee ISO/TC 112, Vacuum technology. BS ISO 213582007 w w w . b z f x w . c o m iv Introduction There has previously been no International Standard for the mounting dimensions of right-angle valves, in spite of the fact that right-angle valves are frequently incorporated in vacuum systems as part of pipeline fittings in practical situations of use. This International Standard was prepared in accordance with the revision of ISO 9803 in which the mounting dimensions of pipeline fittings have been standardized. Interfaces for pneumatic actuators have also been standardized.

This International Standard covers right-angle valves with flanges defined in ISO 2861-1, ISO 1609 and ISO 3669. ISO 3669 lists two flange series ⎯ preferred series, and ⎯ secondary series. This International Standard covers only the valves with flanges of the secondary series. 2 Normative references The following referenced documents are indispensable for the application of this document.
