ÖNORM EN 737-1

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 rnedical gases: oxygen; nitrous oxide; air for breathing; carbon dioxide; oxygednitrous oxide mixture (50/50 % (VN)) 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 mit; 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 mit (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)
