39、-pressure flexible connections shall, when transported, stored, installed, operated 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

40、 connected with their intended application, in normal condition and in single 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

41、to be in compliance with the safety objectives 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 a

42、vailable. Evidence that an equivalent degree of safety is obtained shall be provided 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 med

43、ical gases and with 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 will burn violent

44、ly 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 for ignition in oxygen. Many such materials can be ignited by friction at a valve seat or by adiabatic com

45、pression produced when oxygen at high pressure is rapidly introduced into a system initially at low pressure. NOTE 3 Criteria for the selection of metallic and non-metallic materials are given in ISO 15001. 5.3.2 * Non-metallic (e.g. polymer-lined or rubber-reinforced) flexible hoses shall not be us

46、ed. 5.3.3 The materials shall permit the high-pressure flexible connections and their components to meet the requirements of 5.4 in the temperature range of 20 C to + 60 C. NOTE Regional or national environmental conditions may require deviation from this range of temperatures. 5.3.4 High-pressure f

47、lexible connections shall meet the requirements of this International Standard after being packed for transport and storage and after being exposed to environmental conditions as stated by the manufacturer. 5.3.5 Evidence of conformity with the requirements of 5.3.1, 5.3.3 and 5.3.4 shall be provide

48、d by the manufacturer upon request. 5.4 Design requirements 5.4.1 Inlet connector The inlet connector, for connection to the cylinder valve, shall be gas-specific and conform to ISO 407, ISO 5145 or the relevant regional or national standard (see ISO/TR 7470 for information). DIN EN ISO 21969:2010-0

49、4 EN ISO 21969:2009 (E) 7 5.4.2 Outlet connector 5.4.2.1 The outlet connector shall be one of the following: a) a connector for connection to the manifold; b) a connector for connection to the inlet port of medical equipment; this connector shall be the cylinder valve outlet for the specific medical gas, in accordance with ISO 407, ISO 5145 or the relevant national standard (see ISO/TR 7470 for information). 5.4.2.2 Means shall be provided to prevent the installation of an incorrect high-pressure flexib
