This European Prestandard (ENV) was approved by CEN on 18 December 2002 as a prospective standard for provisional application.
The period of validity of this ENV is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the ENV can be converted into a European Standard.
CEN members are required to announce the existence of this ENV in the same way as for an EN and to make the ENV available promptly
at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the ENV) until the final
decision about the possible conversion of the ENV into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece,
Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and United
Kingdom.

Foreword
This document (ENV 737-6:2003) has been prepared by Technical Committee CEN/TC 215 "Respiratory and
anaesthetic equipment" the secretariat of which is held by BSI as a Special Status European Prestandard (ENV).
EN 737 consists of the following Parts under the general title “Medical gas pipeline systems”:
Part 1: Terminal units for compressed medical gases and vacuum
Part 2: Anaesthetic gas scavenging disposal systems – Basic requirements
Part 3: Pipelines for compressed medical gases and vacuum
Part 4: Terminal units for anaesthetic gas scavenging systems
Part 6: Dimensions and allocation of probes for terminal units for compressed medical gases and vacuum
Taking into account that:
• there are CEN member countries using terminal units and probes which comply with EN 737-1 and which
have dimensions of probes complying with the national standards of Austria (ÖNORM 7387 series), France
(AFNOR NF S 90-116), Germany (DIN 13260, Teil 2), Italy (UNI 9507), Sweden (SS 87 524 30) and United
Kingdom (BS 5682);
• there are CEN member countries using terminal units and probes of existing proprietary design which
comply with EN 737-1 and which have published gas-specific dimensions and tolerances;
• some of these national standards and proprietary designs have a special status defined by law or
regulation and cannot therefore be changed or withdrawn;
this document is published as a Special Status European Prestandard (ENV) for the following reasons:
• CEN members will not be bound to implement the ENV; they need only make the ENV available at national
level in the form of e.g. "Draft for development";
• the dimensions of probes given in the conflicting national standards listed above will not be withdrawn and may
be kept in force in parallel to those given in the European Prestandard;
• terminal units and probes which comply with EN 737-1 and which have dimensions complying with the
conflicting national standards listed above may continue to be installed and used for both new installations and
extensions of existing installations as specified by appropriate National Authorities;
• terminal units and probes of existing proprietary design which comply with EN 737-1, which have published
gas-specific dimensions and tolerances may continue to be installed and used for both new installations and
extensions of existing installations as specified by appropriate National Authorities, provided that it is neither
possible for probes complying with ENV 737-6 to lock into and/or release gas from sockets complying with
each proprietary design nor possible for probes complying with each proprietary design to lock into and to
release gas from sockets complying with ENV 737-6;
• it will be possible to install and use terminal units and probes complying with EN 737-1 and this European
Prestandard for field trials in health care facilities by agreement with appropriate National Authorities.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to announce this European Prestandard: Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,
Slovakia, Spain, Sweden, Switzerland and the United Kingdom.

Introduction
Terminal units are the points on a medical gas supply system where the operator makes connections and
disconnections for the supply of specified medical gases to anaesthetic machines, lung ventilators or other items of
medical equipment, and where a wrong connection can create a hazard to the life of a patient. Connection of
medical equipment to a terminal unit is made by inserting a gas-specific probe into a gas-specific connection point
on the appropriate terminal unit. Both the probe and the terminal unit are be gas-specific to ensure that the correct
gas is delivered to the medical equipment.
It is important therefore that probes and the corresponding gas-specific connection points are designed and
manufactured in such a way as to meet the requirements specified in this European Prestandard.
This European Prestandard gives the dimensions and allocation of probes and the corresponding gas-specific
connection points, in order to ensure that only one design of probe is used for each specified medical gas.
