Flow-metering devices for connection to terminal units of medical gas pipeline systems (ISO 15002:2008)
Abstract
ISO 15002:2008 is applicable to:
- flow-metering devices that are connected, either directly or by means of flexible connecting assemblies, and disconnected by the operator at terminal units of a medical gas pipeline system for flow adjustment, measurement and delivery of medical gases;
- flow-metering devices that are connected and disconnected by the operator at gas-specific connection points of devices such as pressure regulators.
ISO 15002:2008 is applicable to:
- flow-metering devices intended to be used with the following medical gases:
- oxygen;
- nitrous oxide;
- medical air;
- carbon dioxide;
- oxygen/nitrous oxide mixture [50 %/50 % (by volume)]
- specified mixtures of the gases listed above;
- flow-metering devices intended to be used with the following gases:
- oxygen-enriched air;
- helium;
- xenon.
