20、rectly to a patient. These devices need to deliver accurate flows under varying conditions 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 (me

21、chanical strength, safe relief of excess pressure, resistance to ignition); gas specificity; 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

22、and subclauses marked with an asterix (*) after their number have corresponding rationale 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 con

23、sidered that knowledge of the reasons for the requirements will not only facilitate the proper application of this International Standard, but will expedite any subsequent revisions.

24、ope 1.1 This International Standard is applicable to: flow-metering devices that are connected, either directly or by means of flexible connecting assemblies, and disconnected by the operator at terminal units of a medical gas pipeline system for flow adjustment, measurement and delivery of medical

25、gases; flow-metering devices that are connected and disconnected by the operator at gas-specific connection points of devices such as pressure regulators. 1.2 This International Standard applies to: a) flow-metering devices intended to be used with the following medical gases: oxygen; nitrous oxide;

26、 medical air; carbon dioxide; oxygen/nitrous oxide mixture 50 %/50 % (by volume); specified mixtures of the gases listed above; b) flow-metering devices intended to be used with the following gases: oxygen-enriched air; helium; xenon. NOTE Regional or national regulations might permit use of oxygen-

27、specific connection points for oxygen-enriched air. 1.3 This International Standard does not apply to electrical or electronic flow-metering devices. 1.4 This International Standard does not apply to gases used for driving surgical tools.

43、B. 5 General requirements NOTE Unless otherwise specified, pressures in this International Standard are expressed as gauge pressures (i.e. atmospheric pressure is defined as 0). 5.1 Safety Flow-metering devices shall, when transported, stored, installed, operated in normal use and maintained accordi

44、ng to the instructions of the manufacturer, present no risks that are not reduced to an acceptable level using procedures in accordance with ISO 14971 and which are connected with their intended application, in normal conditions and in single fault conditions. 5.2 Alternative construction Flow-meter

45、ing devices, and components or parts thereof, using materials or having forms of construction different from those detailed in this clause (except for dimensions and allocation of DISS and NIST connectors and probes used as inlet connectors), shall be presumed to be in compliance with the safety obj

46、ectives of this International Standard if it can be demonstrated that an equivalent degree of safety is obtained (i.e. compliance with requirements presumes that risks have been mitigated to acceptable levels) unless objective evidence to the contrary becomes available. NOTE 1 Objective evidence mig

47、ht be obtained by postmarket surveillance. Evidence of an equivalent degree of safety shall be provided by the manufacturer upon request. NOTE 2 Regional or national regulations may require the provision of evidence to a competent authority or conformity assessment body (e.g. notified body in the Eu

48、ropean Economic Area) upon request. NOTE 3 Attention is drawn to ISO 14971 on risk management and to the International Standards under development by ISO/TC 210. 5.3 Materials 5.3.1 *The materials in contact with the gases listed in 1.2, during normal use, shall be resistant to corrosion and compati

49、ble with oxygen and the other gases and their mixtures in the temperature range specified in 5.3.3. NOTE 1 Corrosion resistance includes resistance against moisture and surrounding materials. NOTE 2 Compatibility with oxygen involves both combustibility and ease of ignition. Materials that burn in air burn violently in pure oxygen. Many materials that do not burn in air will do so in pure oxygen, particularly under pressure. Similarly, materials that can be ignited in air, require lower ignition energies in oxyge
