Flow-metering devices for connection to terminal units of medical gas pipeline systems
|Publication Date:||1 January 2012|
|ICS Code (Anaesthetic, respiratory and reanimation equipment):||11.040.10|
This International Standard 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.
This International Standard applies to:
a) flow-metering devices intended to be used with the following medical gases:
⎯ nitrous oxide;
⎯ medical air;
⎯ carbon dioxide;
⎯ oxygen/nitrous oxide mixture [50 %/50 % (by volume)];
⎯ specified mixtures of the gases listed above;
b) flow-metering devices intended to be used with the following gases:
⎯ oxygen-enriched air;
NOTE Regional or national regulations might permit use of oxygen-specific connection points for oxygen-enriched air.
This International Standard does not apply to electrical or electronic flow-metering devices.
This International Standard does not apply to gases used for driving surgical tools.
