24、aphy13 BS EN ISO 21969:2009ISO 21969:2009(E) iv ISO 2009 All rights reservedForeword 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
25、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 the work. ISO collaborates clo
26、sely 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 prepare International Standards. Dra
27、ft 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 some of the elements of this docu
28、ment may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 21969 was prepared by Technical Committee ISO/TC 121, Anaesthetic and respiratory equipment, Subcommittee SC 6, Medical gas systems. This second edition cancels and replaces
29、 the first edition (ISO 21969:2005) which has been technically revised. Annex A contains rationale statements for some of the requirements of this International Standard. It is included to provide additional insight into the reasoning that led to the requirements and recommendations that have been i
30、ncorporated in this International Standard. The clauses and subclauses marked with an asterisk (*) after their number have corresponding rationale contained in Annex A. It is considered that knowledge of the reasons for the requirements will not only facilitate the proper application of this Interna
31、tional Standard, but will also expedite any subsequent revision.

33、tools; nitrogen for driving surgical tools; oxygen-enriched air. 1.2 This International Standard applies to high-pressure flexible connections intended to connect cylinders or cylinder bundles to manifolds within sources of supply of medical gas pipeline systems complying with ISO 7396-1. 1.3 This I

44、rated in normal use and maintained according to the instructions of the manufacturer, present no risks that are not reduced to an acceptable level using risk management procedures in accordance with ISO 14971 and which are connected with their intended application, in normal condition and in single
45、fault condition. 5.2 Alternative construction High-pressure flexible connections and components or parts thereof, using materials or having forms of construction different from those detailed in Clause 5 shall be presumed to be in compliance with the safety objectives of this International Standard
46、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. Evidence that an equivalent degree of safety is obtained shall be pr
47、ovided by the manufacturer upon request. 5.3 Materials 5.3.1 * The materials in contact with the medical gases listed in 1.1, during normal use shall be resistant to corrosion and compatible with oxygen, with the other medical gases and with their mixtures in the temperature range specified in 5.3.3
48、. 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 will burn violently in pure oxygen. Many materials that do not burn in air will do so in pure o
49、xygen, particularly under pressure. Similarly, materials that can be ignited in air require lower ignition energies for ignition in oxygen. Many such materials can be ignited by friction at a valve seat or by adiabatic compression produced when oxygen at high pressure is rapidly introduced into a system initially at low pressure.
