The work of preparing International Standards is no
13、rmally 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
14、 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 prepa
15、re 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 so
16、me 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 17292 was prepared by Technical Committee ISO/TC 153, Valves, Subcommittee SC 1, Design, manufacture, marking and testing in collaboration wit

20、m Institute Standard API 608. It is not the purpose of this International Standard to replace ISO 7121 or any other International Standard that is not identified with petroleum refinery, petrochemical or natural gas industry applications. In this International Standard, flanged end Class-designated
21、valves have flanges in accordance with ASME B16.5. Flanged end PN-designated valves have flanges in accordance with EN 1092-1. Valves with ends threaded may have threads to either ISO 7-1 or ASME B1.20.1. Copyright International Organization for Standardization Provided by IHS under license with ISO

43、is International Standard shall be the lesser of the shell rating (see 4.2) or the seat rating (see 4.3). 4.2 Shell rating 4.2.1 The pressure/temperature ratings applicable to the valve pressure containing shell (the pressure boundary elements e.g. body, body cap, trunnion cap, cover, body inserts)
44、shall be in accordance with those specified in the pressure/temperature tables of either ASME B16.34, Standard Class for Class- designated valves, or EN 1092-1 for PN-designated valves. 4.2.2 The temperature for a corresponding shell pressure rating is the maximum temperature that is permitted for t
45、he pressure containing shell of the valve. In general, this maximum temperature is that of the contained fluid. The use of a pressure rating corresponding to a temperature other than that of the contained fluid is the responsibility of the user. For temperatures below the lowest temperature listed i
46、n the pressure/temperature tables (see 4.2.1), the service pressure shall be no greater than the pressure for the lowest listed temperature. Consideration should be given to the loss of ductility and impact strength of many materials at low temperature. Copyright International Organization for Stand
