CAN/CSA-Z10524-02 (R2007)

This National Standard of Canada is based on International Standard ISO 10524:1995. 1 Scope 1.1 This International Standard specifies requirements for pressure regulators and pressure regulators with flow-metering devices intended for the administration of medical gases in the treatment, management, diagnostic evaluation and care of patients. It applies to the types of pressure regulators given in a) and c) for use with the following medical gases: air carbon dioxide helium oxygen nitrogen nitrous oxide xenon mixtures of oxygen and carbon dioxide mixtures of oxygen and helium mixtures of oxygen and nitrogen mixtures of oxygen and nitrous oxide The types of pressure regulators are as follows: a) high-pressure regulators (inlet pressure up to 20 000 kPa) intended to be connected by the user to high-pressure gas cylinders; c) low-pressure regulators (inlet pressure up to 1 400 kPa) intended to be connected by the user to terminal units of medical gas pipeline systems. This International Standard also applies to the following types of pressure regulators with flow-metering devices: d) pressure regulators with integral flow-metering devices as described in a) and c); e) pressure regulators with flow-metering devices that are not integral with the types of pressure regulators described in a) and c) but are not intended to be detached from the pressure regulator by the user. 1.2 This International Standard does not apply to a) high-pressure and low-pressure regulators that are an integral part of medical gas pipeline systems; b) low-pressure regulators, with or without flow-metering devices, that are an integral part of medical equipment; c) pressure regulators integrated within cylinder valves; d) vacuum regulators. dA) high-pressure regulators (inlet pressure up to 20 000 kPa) that are an integral part of medical equipment (e.g., anaesthetic machines, lung ventilators, resuscitators).
