This document specifies requirements for flow control devices that can be connected by the user either directly, by means of a probe or a gas-specific connector, or indirectly by means of a low-pressure hose assembly conforming with ISO 5359 to:
a) a terminal unit conforming with ISO 9170-1 of a medical gas pipeline system conforming with ISO 7396-1:2016;
b) the pressure outlet of a regulator conforming with ISO 10524-1:2018; or
c) to the pressure outlet of a valve integrated pressure regulator (VIPR) conforming with ISO 10524-3 (see 5.2 gas inlets).
This document applies to the following types of flow control devices (FCDs):
a) flowmeters;
b) flowgauge FCDs; and
c) fixed orifice FCDs.
NOTE Flow control devices that are classed as medical electrical equipment can be subject to additional requirements of IEC 60601-1.
This document applies to flow control devices for the following gases:
— oxygen;
— oxygen 93 %;
— nitrous oxide;
— medical air;
— carbon dioxide;
— oxygen/nitrous oxide mixture 50/50 (% volume fraction);
— oxygen-enriched air;
— helium;
— xenon; and
— specified mixtures of the gases listed above.
NOTE Flow control devices can be available for other gases.
This document does not apply to flow control devices that are:
a) for use with gases for driving surgical tools;
b) an integral part of a regulator (see ISO 10524-1:2018); or
c) an integral part of a valve with integrated pressure regulator (VIPR) (see ISO 10524-3).
