EN 738-1:1997

EN 738-1:1997 is a standard published by the European Committee for Standardization (CEN). Its full title is "Pressure regulators for use with medical gases - Part 1: Pressure regulators and pressure regulators with flow metering devices". This standard covers: 1.1 This Part of this European Standard applies to pressure regulators intended for the administration of medical gases in the treatment, management, diagnostic evaluation and care of patients and applies to the types of pressure regulator given in 1.1 a), b) and c) and to the types of flow metering devices given in 1.1 d) and e) for use with the following medical gases: - oxygen - nitrous oxide - air for breathing - helium - carbon dioxide - xenon - specified mixtures of the gases listed above - air for driving surgical tools - nitrogen for driving surgical tools a) High pressure regulators (up to 20 000 kPa) intended to be connected by the operator to high pressure gas cylinders; b) High pressure regulators (up to 20 000 kPa) that are an integral part of, or are permanently connected to, medical equipment (e.g. anaesthetic workstations, lung ventilators, resuscitators); c) Low pressure regulators (up to 1400 kPa) intended to be connected by the operator to the terminal units of medical gas pipeline systems; d) Flow metering devices that are integral with the types of pressure regulator described in 1.1 a) and 1.1 c); e) Flow metering devices that are not integral with the types of pressure regulator described in 1.1 a) and 1.1 c) but are not intended to be detached from the pressure regulator by the operator. 1.2 This standard does not apply to the following types of pressure regulator: a) High pressure and low pressure regulators that are an integral part of medical gas pipeline systems (see prEN 738-2); b) Pressure regulators integrated with cylinder valves (see prEN 738-3); c) Low pressure regulators, with or without flow metering devices that are an integral part of medical equipment (see prEN 738-4); d) Pressure regulators for use with suction services. (See EN ISO 10079-3)

EN 738-1:1997 is classified under the following ICS (International Classification for Standards) categories: 11.040.10 - Anaesthetic, respiratory and reanimation equipment; 23.060.40 - Pressure regulators. The ICS classification helps identify the subject area and facilitates finding related standards.

EN 738-1:1997 has the following relationships with other standards: It is inter standard links to EN ISO 10524-1:2006, EN 738-1:1997/A1:2002; is excused to EN 738-2:1998, EN 738-3:1998, EN 738-4:1998. Understanding these relationships helps ensure you are using the most current and applicable version of the standard.

EN 738-1:1997 is associated with the following European legislation: EU Directives/Regulations: 93/42/EEC; Standardization Mandates: M/023. When a standard is cited in the Official Journal of the European Union, products manufactured in conformity with it benefit from a presumption of conformity with the essential requirements of the corresponding EU directive or regulation.
