These devices need to deliver accurate flows under varying con
32、ditions of temperature and inlet pressure. Therefore it is important that the operating characteristics be specified and tested in a defined manner. This International Standard pays particular attention to: safety (mechanical strength, safe relief of excess pressure, resistance to ignition); gas spe
33、cificity; cleanliness; suitability of materials; accuracy; testing; identification; information supplied. Annex A contains rationale statements for some of the requirements of this International Standard. The clauses and subclauses marked with an asterix (*) after their number have corresponding rat
34、ionale contained in informative Annex A, included to provide additional insight into the reasoning that led to the requirements and recommendations that have been incorporated in this International Standard. It is considered that knowledge of the reasons for the requirements will not only facilitate
35、 the proper application of this International Standard, but will expedite any subsequent revisions. 4 DIN EN ISO 15002:2008-11 EN ISO 15002:2008 (E) 1 Scope 1.1 This International Standard is applicable to: flow-metering devices that are connected, either directly or by means of flexible connecting
36、assemblies, and disconnected by the operator at terminal units of a medical gas pipeline system for flow adjustment, measurement and delivery of medical gases; flow-metering devices that are connected and disconnected by the operator at gas-specific connection points of devices such as pressure regu
37、lators. 1.2 This International Standard applies to: a) flow-metering devices intended to be used with the following medical gases: oxygen; nitrous oxide; medical air; carbon dioxide; oxygen/nitrous oxide mixture 50 %/50 % (by volume); specified mixtures of the gases listed above; b) flow-metering de
38、vices intended to be used with the following gases: oxygen-enriched air; helium; xenon. NOTE Regional or national regulations might permit use of oxygen-specific connection points for oxygen-enriched air. 1.3 This International Standard does not apply to electrical or electronic flow-metering device
39、s. 1.4 This International Standard does not apply to gases used for driving surgical tools. 5 DIN EN ISO 15002:2008-11 EN ISO 15002:2008 (E) 2 *Normative references The following referenced documents are indispensable for the application of this document.
