BS EN ISO 10524-4:2008

This standard BS EN ISO 10524-4:2008 Pressure regulators for use with medical gases is classified in these ICS categories:

• 11.040.10 Anaesthetic, respiratory and reanimation equipment

1.1 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.

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

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

2. 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;

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

4. 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.

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