1.1
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.
1.2
This International Standard applies 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.
-
NOTE Regional or national regulations might permit use of oxygen-specific connection points for oxygen-enriched air.
1.3
This International Standard does not apply to electrical or electronic flow-metering devices.
1.4
This International Standard does not apply to gases used for driving surgical tools.
