30、07+A1:2012 (E)31333730vForeword 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 bodyinterested in a
31、 subject for which a technical committee has beenestablished 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 closelywith the International Electrotechnical Commission
32、(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 Standardsadopted by the technical commit
33、tees are circulated to the member bodies for voting. Publication as an International Standard requires approval byat 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
34、held responsible for identifying any or all such patent rights. ISO22435 was prepared by Technical Committee ISO/TC58, Gas cylinders, Subcommittee SC 2, Cylinderfittings. EN ISO 22435:2007BS EN ISO 22435:2007+A1:2012ISO 22435:2007+A1:2012 (E)vi Introduction Cylinder valveswith integrated pressure re
35、gulators are used to reduce the high cylinder pressure to a lowerpressure suitable for use. These functions cover a wide range of inlet and outlet pressures and flowswhich require specific designcharacteristics. It is important that the operating characteristics of these valves be specified and test
36、ed in adefined manner. Such valves are more complicated than conventional cylinder valvesyet subject to the same environmental and transportation conditions. These conditions should be borne in mind at the design and development stage. ThisInternational Standardpays particular attention to suitabili
37、ty of materials, safety (mechanical strength, safe relief of excess pressure and resistance to ignition), gas-specificity, cleanliness, testing, identification,and information supplied.

This International Standard is not intended for
39、medical applications (see ISO 10524-3). Further, additional specific requirements for valves fitted with safetyvalves and bursting discs (see EN14513) and for valves fitted with residual pressure valves (see ISO 15996) are not covered by this International Standard. 2 NormativereferencesThe followin
