15、word 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 technical committees. Each member body interested in a subject for which a techn
16、ical 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 closely with the International Electrotechnical Commission (IEC) on all matters of
17、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. Draft International Standards adopted by the technical committees are circulated to
18、 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 document may be the subject of patent rights. ISO shall not be held responsible for
19、identifying any or all such patent rights. ISO 10524-3 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: Par

22、e 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 specific design characteristics. It is important that the operating characterist
23、ics of pressure regulators integrated with cylinder valves be specified and tested in a defined manner. A pressure regulator normally has coupled to it a device which controls the flow, such as a flow control valve or a fixed orifice. The flow can be indicated by a flowmeter or by a flowgauge. It is
24、 essential that regular inspection and maintenance be undertaken to ensure 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 ex
