EN 737-1:1998

EN 737-1:1998 is a standard published by the European Committee for Standardization (CEN). Its full title is "Medical gas pipeline systems - Part 1: Terminal units for compressed medical gases and vacuum". This standard covers: 1.1 This Part of this European Standard specifies requirements for terminal units intended for use in medical gas pipeline systems specified in prEN 737-3 for use with the following medical gases: - oxygen; - nitrous oxide; - air for breathing; - carbon dioxide; - oxygen/nitrous oxide mixture (50/50 % (V/V)) - air for driving surgical tools; - nitrogen for driving surgical tools - vacuum. It is intended especially to ensure the gas-specific assembly of terminal units and to prevent their interchange between different gases. 1.2 This Part of this European Standard also specifies requirements for: - terminal units for the supply and disposal of air for driving surgical tools; - probes intended to be connected to the gas-specific connection point which is part of a terminal unit; 1.3 This Part of this European Standard does not specify: - the dimensions of probes and of the gas-specific connection points of the terminal unit (see prEN 737-6); - the dimensions of NIST connectors (see EN 739); - requirements for terminal units for anaesthetic gas scavenging systems (see EN 737-4)

EN 737-1:1998 is classified under the following ICS (International Classification for Standards) categories: 11.040.10 - Anaesthetic, respiratory and reanimation equipment; 23.040.60 - Flanges, couplings and joints; 23.060.01 - Valves in general. The ICS classification helps identify the subject area and facilitates finding related standards.

EN 737-1:1998 has the following relationships with other standards: It is inter standard links to EN ISO 9170-1:2008, EN 14931:2006, EN 1789:2007+A2:2014, EN 1789:2007+A1:2010. Understanding these relationships helps ensure you are using the most current and applicable version of the standard.

EN 737-1:1998 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.
