适用范围：1.1 This International Standard specifies minimum require-ments for the installation, construction, function, documen-tation and testing of non-flammable medical gas pipeline systems to ensure patient safety by delivery of the correct gas from the pipeline system. It includes requirements for the source of supply, distribution system, terminal units, warning systems, and for non-interchangeability between key com-ponents and service outlets.1.2 It applies only to pipeline systems for the following non-flammable medical gases:a) oxygen;b) nitrous oxide;c) medical air;d) nitrogen;e) helium11;f) carbon dioxide;g) specified mixtures of the gases listed in a) to f); h) medical vacuum.1.3 It applies to pipeline systems used at pressures required for patient care, including therapeutic, diagnostic and prophy-lactic applications and surgical tool applications. Pipeline systems used for non-clinical purposes are excluded. A medical air pipeline, supplied from an air compressor system only, may be extended to applications not directly related to patient care and certain precautions are given in annex G, for applications such asa) the operation of ceiling columns in theatres;b) anaesthetic waste gas systems;c) sterilizer departments;d) breathing air for surgical personnel;e) pneumatic control of air conditioning;f) testing of medical equipment.Extensions are not permitted for applications such as a) general workshop use; b) motor repair workshops;c) spray painting;d) tyre inflation.e) those which may impose unforeseen demands, which could prejudice the availability and/or quality of medical air for normal patient care purposes;f) reservoirs for pressurization of hydraulic fluids.
