The work of preparing
23、 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 has the right to be represented on that committee. International organizations, governmental and non-governmental, in liais
24、on with ISO, also take part in the work. ISO collaborates closely 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 te
25、chnical committees is to prepare International Standards. Draft 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 dr
26、awn 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 rights. ISO 10524-1 was prepared by Technical Committee ISO/TC 121, Anaesthetic and respiratory equipment, Subcommittee SC 6
27、, Medical gas systems. This first edition cancels and replaces ISO 10524:1995 and ISO 10524:1995/Cor 1:1996, which has been technically revised. ISO 10524 consists of the following parts, under the general title Pressure regulators for use with medical gases: Part 1: Pressure regulators and pressure
28、 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 For the purposes of this part of ISO 10524, the CEN annex regarding fulfilment of European Council Directives has been remo
29、ved. EN ISO 10524-1:2006vIntroduction A pressure regulator is used to reduce high cylinder pressure to a lower pressure suitable for use with medical equipment or for delivery of gas directly to a patient. These functions cover a wide range of inlet and outlet pressures and flows which require speci
30、fic design characteristics. It is important that the operating characteristics of the pressure regulators are specified and tested in a defined manner. A pressure regulator often has coupled to it a device which controls the flow, such as a flow control valve or a fixed orifice. The flow can be indi
31、cated by a flowmeter or by a flowgauge. It is essential that regular inspection and maintenance are undertaken to ensure that 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 (mecha
32、nical strength, leakage, safe relief of excess pressure and resistance to ignition); gas specificity; cleanliness; type testing; 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
33、 marked with an asterix (*) after their number have corresponding rationale, contained in Annex B, included to provide additional insight into the reasoning that led to the requirements and recommendations that have been incorporated in this part of ISO 10524. It is considered that knowledge of the
34、reasons for the requirements will not only facilitate the proper application of this part of ISO 10524, but will expedite any subsequent revisions.

35、 Scope 1.1 This part of ISO 10524 is applicable to the types of pressure regulators listed in 1.3 intended for the administration of the following medical gases in the treatment, management, diagnostic evaluation and care of patients: oxygen; nitrous oxide; air for breathing; helium; carbon dioxide;
36、 xenon; mixtures of the gases listed above; air for driving surgical tools; nitrogen for driving surgical tools. 1.2* These pressure regulators are intended to be fitted to cylinders with nominal filling pressures up to 25 000 kPa at 15 C and can be provided with devices which control and measure th
37、e flow of the medical gas delivered. 1.3 The types of pressure regulators covered by this part of ISO 10524 are as follows: a) pressure regulators intended to be connected to cylinders by the operator; b) pressure regulators with integral flow-metering devices intended to be connected to cylinders b
38、y the operator; c) pressure regulators that are an integral part of medical equipment (e.g. anaesthetic workstations, lung ventilators, resuscitators).
