Abstract

1.1 This European Standard specifies basic requirements for installation, function, performance, documentation, testing and commissioning of compressed medical gases and vacuum pipeline systems to ensure patient safety by continuous delivery of the correct gas from the pipeline system. It includes basic requirements for the sources of supply, distribution system, control, monitoring and alarm systems and for non-interchangeability between components of different gas systems. The objective of this Part of this European Standard is to ensure the following : a) design of equipment to ensure non-interchangeability between different gas systems; b) provision of reserve supplies of gas and reserve plant in order to ensure continuous supply; c) use of correct materials, and their cleanliness; d) correct installation; e) control, monitoring and alarm systems; f) marking of the pipeline system; g) testing, commissioning and certification; h) purity of the gases delivered by the system. The scope of this European Standard does not include the provision of gas-specific connectors for mobile and stationary cryogenic vessels and transport vehicles, nor for the inlet/outlet of non-cryogenic liquid and gas cylinders. Such gas-specific connectors, however, are essential to ensure that only the correct gas can be used for the gas supply to the patient. 1.2 This European Standard applies only to pipeline systems for the following medical gases : - oxygen - nitrous oxide - air for breathing - carbon dioxide - oxygen/nitrous oxide mixture (50:50%V/V) - air for driving surgical tools - nitrogen for driving surgical tools and to pipeline systems for : - vacuum. 1.3 This European Standard does not apply to terminal units, dimensions of probes, hose assemblies and colour coding for medical gases which are specified in other parts of this European Standard (EN 737-1 and prEN 737-6 : 1996) and in other European Standards (EN 739). 1.4 This European Standard does not apply to pipeline systems supplied by oxygen concentrators which comply with ISO 10083.
