scope:

ABSTRACT This International Standard specifies minimum requirements for the oxygen compatibility of materials, components and devices for anaesthetic and respiratory applications which can come i n contact with oxygen in normal condition or in single fault condition at gas pressures greater than 50 kPa. This International Standard is applicable to anaesthetic and respiratory equipment which are within the scope of ISO/TC 121, e.g. pipeline systems, pressure regulators, terminal units, medical supply units, flexible connecting assemblies, flow-metering devices, anaesthetic workstations and lung ventilators. Aspects of compatibility that are addressed by this International Standard include cleanliness, resistance to ignition and the toxicity of products of combustion and/or decomposition.
