scope:

This part of ISO 10524 applies to the types of low-pressure regulators listed in 1.2 and intended to be used with the following medical gases in the treatment, management, diagnostic evaluation and care of patients:

- oxygen;

- nitrous oxide;

- medical air;

- helium;

- carbon dioxide;

- xenon;

- specified mixtures of the gases listed above;

- air for driving surgical tools;

- nitrogen for driving surgical tools;

- oxygen-enriched air.

The types of low-pressure regulators covered by this part of ISO 10524 are as follows:

a) low-pressure regulators intended to be connected to terminal units of medical gas pipeline systems complying with ISO 7396-1;

b) low-pressure regulators with integral flow-metering devices intended to be connected to terminal units of medical gas pipeline systems complying with ISO 7396-1;

c) low-pressure regulators intended to be connected to terminal units attached to pressure regulators complying with ISO 10524-1 or ISO 10524-3;

d) operator-adjustable low-pressure regulators for air or nitrogen for driving surgical tools that are an integral part of a medical gas pipeline system complying with ISO 7396-1.

This part of ISO 10524 does not apply to low-pressure regulators integrated within anaesthetic and respiratory equipment.
