CSA Z10524-3:19 (R2024)

CSA Preface This is the second edition of CSA Z10524-3, Pressure regulators for use with medical gases — Part 3: Pressure regulators integrated with cylinder valves (VIPRs), which is an adoption, with Canadian deviations, of the identically titled ISO (International Organization for Standardization) Standard 10524-3 (second edition, 2019-01). It supersedes the previous edition published in 2012 as CAN/CSA-Z10524-3 (adopted ISO 10524-3:2005). This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope This document specifies design, type testing, and marking requirements for cylinder valves with integrated pressure regulators [as defined in 3.26 and referred to hereafter as valves with integrated pressure regulators (VIPRs)] intended for the administration of medical gases in the treatment, management, diagnostic evaluation and care of patients or for gases used for driving surgical tools. Examples of gases include oxygen, medical air and oxygen/nitrous oxide mixtures. This document applies to VIPRs mounted on refillable cylinders with a working pressure up to 30 000 kPa (300 bar) intended to be filled in cylinder filling facilities or on self-filling systems as used in homecare applications. VIPRs covered by this document are pressure pre-set and provided with a pressure outlet and/or pre-set flow outlet(s).

It supersedes the previous edition published in 2012 as CAN/CSA-Z10524-3 (adopted ISO 10524-3:2005). For brevity, this Standard will be referred to as “CSA Z10524-3” throughout. This Standard was reviewed for Canadian adoption by the CSA Subcommittee on Medical Gas Systems, under the jurisdiction of the CSA Technical Committee on Perioperative Safety and the CSA Strategic Steering Committee on Health and Well-being, and has been formally approved by the Technical Committee.
