CSA Z10524-1:19 (R2024)

CSA Preface This is the second edition of CSA Z10524-1, Pressure regulators for use with medical gases — Part 1: Pressure regulators and pressure regulators with flow-metering devices, which is an adoption, with Canadian deviations, of the identically titled ISO (International Organization for Standardization) Standard 10524-1 (second edition, 2018-01). It supersedes the previous edition published in 2012 as CAN/CSA-Z10524-1 (adopted ISO 10524-1:2006). For brevity, this Standard will be referred to as “CSA Z10524-1” 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. 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 the design, construction, type testing, and marking requirements for pressure regulators (as defined in 3.18) intended for the administration of medical gases and their mixtures 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 pressure regulators: a) intended to be connected to cylinders by the operator; b) with integral flow-metering devices intended to be connected to cylinders by the operator; c) that are an integral part of medical equipment (e.g. anaesthetic workstations, lung ventilators, resuscitators). A pressure regulator can be provided with pressure outlet or flow outlet, and can be adjustable or pre-set. Pressure regulators are intended to be fitted to refillable cylinders with a working pressure up to 30 000 kPa ( 300 bar) and can be provided with devices which control and measure the flow of the medical gas delivered.
