CSA Z10524-4:12 (R2022)

CSA 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).

This Standard was reviewed for Canadian adoption by the CSA Technical Committee on Perioperative Safety, under the jurisdiction of the CSA Strategic Steering Committee on Health Care Technology, and has been formally approved by the Technical Committee. This Standard has been approved as a National Standard of Canada by the Standards Council of Canada.

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.
