31、and the Essential Requirements of EU Directive 93/42/EEC Medical Devices 33 EN ISO 10524-2:2006 (E) 4 Introduction Manifold pressure regulators are used to reduce cylinder pressure to a lower pressure within a source of supply of a medical gas pipeline system. Line pressure regulators are used to re
32、duce 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 of inlet and outlet pressures and flows which require specific design characteristics. It is imp
33、ortant 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 ensure that the pressure regulators continue to meet the requirements of this part of ISO 10524. T
34、his 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; marking; information supplied by the manufacturer. Annex B contains rationale statements for som
35、e 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 reasoning that led to the requirements and recommendations that have been incorporated into this par
36、t 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. EN ISO 10524-2:2006 (E) 5 1 Scope 1.1* This part of ISO 10524 specifies requirements for manifold
37、 pressure regulators (as defined in 3.6) intended to be connected to cylinders with nominal filling pressures up 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: ox
38、ygen; nitrous oxide; air for breathing; carbon dioxide; oxygen/nitrous oxide mixtures; air for driving surgical 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 supp
39、lied as individual units or to the relevant components incorporated within an assembly. 1.3 This part of ISO 10524 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
