Pertains to the types of low-pressure regulators 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.

Preface This is the first edition of CAN/CSA-Z10524-4, Pressure regulators for use with medical gases - Part 4: Low-pressure regulators, which is an adoption, with Canadian deviations, of the identically titled ISO (International Organization for Standardization) Standard 10524-4 (first edition, 2008-06-01). Scope 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: 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 1.3 This part of ISO 10524 does not apply to low-pressure regulators integrated within anaesthetic and respiratory equipment.
