38、ylinder valves with integrated pressure regulators are used to reduce the high cylinder pressure to a lower pressure suitable for use. These functions cover a wide range of inlet and outlet pressures and flows which require specific design characteristics. It is important that the operating characte

39、ristics of these valves be specified and tested in a defined manner. Such valves are more complicated than conventional cylinder valves yet subject to the same environmental and transportation conditions. These conditions should be borne in mind at the design and development stage. This Internationa

40、l Standard pays particular attention to suitability of materials, safety (mechanical strength, safe relief of excess pressure and resistance to ignition), gas-specificity, cleanliness, testing, identification, and information supplied. 5DIN EN ISO 22435:2013-03 EN ISO 22435:2007 + A1:2012 (E) 1 Scop

41、e This International Standard applies to cylinder valves with integrated pressure regulators (VIPR) intended to be fitted to gas cylinders that convey compressed, liquefied or dissolved gases. This International Standard is not intended for medical applications (see ISO 10524-3). Further, additional

42、 specific requirements for valves fitted with safety valves and bursting discs (see EN 14513) and for valves fitted with residual pressure valves (see ISO 15996) are not covered by this International Standard. 2 Normative references The following referenced documents are indispensable for the applic
