scope:

This European Standard specifies requirements for construction, dimensions and marking of connectors used in gas sampling to transfer gas from the breathing system of anaesthetic and respiratory equipment to diverting gas monitors and back to the breathing system and/or to the anaesthetic gas scavenging system (AGSS).
This European Standard gives requirements for the following ports and connectors:
- gas sampling port on breathing system;
- gas return port on breathing system and AGSS;
- gas sampling and return ports on diverting gas monitors;
- gas sampling tube inlet and outlet connectors;
- gas return tube inlet and outlet connectors.
This European Standard does not apply to connection ports intended for connection of sensors in the breathing system.
According to EN 1707, Luer lock fittings are intended to be used for syringes, needles and certain other medical equipment. In order to minimize the risk of misconnection, this standard specifies the arrangements of male and female fittings and the marking requirements to identify the different connectors, ports and tubes. Tables 1 to 4 specify the type of Luer fitting that is used in actual applications.
NOTE 1 Manufacturers are encouraged to use the ports specified in this standard on diverting gas monitors, breathing systems and AGS systems even if these are currently not required by the specific device standards. It is expected that requirements for the application of this standard will be included in these particular standards during forthcoming revisions. Attention is drawn to EN ISO 21647 concerning respiratory gas monitors and the work of CEN/BT/TF 123 Small-bore connectors. Attention is drawn to the work of CEN BT TF 123 to develop new connectors for use in respiratory applications. Those connectors, when validated and published, will be considered in a future revision of this standard to replace those specified in Clause 5. Further attention is drawn to the need of proper risk management according
