21、tion 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 technical committees. Each member body interested in a subject for which a technical committee has been established
22、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 closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. In
23、ternational 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. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publi
24、cation 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 document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent r
25、ights. ISO 10524-2 was prepared by Technical Committee ISO/TC 121, Anaesthetic and respiratory equipment, Subcommittee SC 6, Medical gas systems. ISO 10524 consists of the following parts, under the general title Pressure regulators for use with medical gases: Part 1: Pressure regulators and pressur
26、e regulators with flow-metering devices Part 2: Manifold and line pressure regulators Part 3: Pressure regulators integrated with cylinder valves Part 4: Low-pressure regulators EN ISO 10524-2:2006vIntroduction Manifold pressure regulators are used to reduce cylinder pressure to a lower pressure wit
27、hin a source of supply of a medical gas pipeline system. Line pressure regulators are used to reduce the pressure supplied by manifold pressure regulators or by cryogenic vessels to the lower pressure required at the terminal units of medical gas pipeline systems. These functions cover a wide range
28、of inlet and outlet pressures and flows which require specific design characteristics. It is important that the operating characteristics of manifold and line pressure regulators are specified and tested in a defined manner. It is essential that regular inspection and maintenance be undertaken to en
29、sure that the pressure regulators continue to meet the requirements of this part of ISO 10524. This part of ISO 10524 pays particular attention to: use of suitable materials; safety (mechanical strength, leakage, safe relief of excess pressure and resistance to ignition); cleanliness; type testing;
30、marking; information supplied by the manufacturer. Annex B contains rationale statements for some of the requirements of this part of ISO 10524. The clauses and subclauses marked with an asterisk (*) after their number have corresponding rationale included to provide additional insight into the reas
31、oning that led to the requirements and recommendations that have been incorporated into this part of ISO 10524. It is considered that knowledge of the reasons for the requirements will not only facilitate the proper application of this part of ISO 10524, but will expedite any subsequent revisions. E
32、N ISO 10524-2:2006blank1Pressure regulators for use with medical gases Part 2: Manifold and line pressure regulators 1 Scope 1.1* This part of ISO 10524 specifies requirements for manifold pressure regulators (as defined in 3.6) intended to be connected to cylinders with nominal filling pressures up
33、 to 25 000 kPa at 15 C and for line pressure regulators (as defined in 3.4) for inlet pressures up to 3 000 kPa and intended for use in pipeline systems for the following medical gases: oxygen; nitrous oxide; air for breathing; carbon dioxide; oxygen/nitrous oxide mixtures; air for driving surgical
34、tools; nitrogen for driving surgical tools; oxygen produced by an oxygen concentrator. 1.2* This part of ISO 10524 applies to manifold pressure regulators and line pressure regulators supplied as individual units or to the relevant components incorporated within an assembly. 1.3 This part of ISO 105
35、24 does not apply to pressure regulators for use with vacuum pipeline systems. NOTE Requirements for pressure regulators for use with vacuum pipeline systems are covered in ISO 10079-3. 2 Normative references The following referenced documents are indispensable for the application of this document.
