Scope:
Reaffirmation
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:
a) 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;
b) 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
