Introduction
Experience relating to escape from buildings, fire and/or smoke hazards and general safety has made it
desirable those doors in circulation areas, or those that have to be operated in an emergency situation, be
fitted with emergency exit devices to common European Standard specifications.
The main purpose of the performance requirements contained in this European Standard is to give safe and
effective escape through a doorway with one single operation to release the emergency exit device, although
this might require prior knowledge of the door situation (e.g. inwardly opening).
The performance tests incorporated in this European Standard are considered to be reproducible and, as
such, will provide a consistent and objective assessment of the performance of these emergency exit devices.
Where panic situations are foreseen, reference should be made to EN 1125, covering panic exit devices
operated by a horizontal bar. See definition 3.18.
Where additional security is required for exit doors, reference should be made to EN 13637 covering
electrically controlled exit systems for use on escape routes. See Bibliography.
Due to the wide range of emergency exit devices, the reader is advised to refer to the scope and the detailed
contents of this European Standard for coverage but, for information and general guide, this revised European
Standard deals with:
Emergency exit devices designed to be used in emergency situations, where people are familiar with the
exit and its hardware and therefore a panic situation is most unlikely to develop;
Emergency exit devices for use on hinged or pivoted door leaves only;
Range of emergency exit devices including those for use on double doorsets (see 7.10);
Three specific types of operation:
emergency exit devices with “lever handle” operation, type A (see 3.9 and figure 1);
emergency exit devices with “push pad” operation, type B (see 3.15 and figure 2);
emergency exit devices with “touch pad” operation type C (see 3.33 and figure 3);
Two categories of emergency exit device projection in order to maximize the width of the escape route,
and minimize the projection from the door face where either or both of these criteria are of importance
(see 4.2.1.6);
Exceptional case of emergency exit devices intended for use on single leaf inwardly opening exit doors. It
is assumed throughout this European Standard that emergency exit doors generally open towards the
outside in order to assure safe escape. However, there are cases such as hospital or hotel bedroom
doors, classroom doors, etc. where local building regulations allow, by way of exception, the exit door to
open against the direction of exit;
double doorset emergency exit devices of which the first opening leaf is equipped with a panic exit device
conforming to EN 1125 and the second opening leaf is equipped with an emergency exit device
conforming to EN 179. It is essential that this combination undergoes an additional test for approval (see
4.6).

This European Standard does not cover the following:
Any particular design of emergency exit devices and only such dimensions as are required for safety
reasons are specified;
Specific emergency exit devices intended for use on inwardly opening double doorsets;
Specific emergency exit devices intended for use by the severely disabled (due to the wide range of
disabilities, such emergency exit devices and their performances should be agreed between user and
manufacturer);
Panic exit devices operated by a horizontal bar (see EN 1125) or electrically controlled exit systems
(EN 13637).
The major changes in this revision are as follows:
Different sealing forces have been introduced for classification of the durability (2nd digit);
Different static closing forces have been introduced for classification of Door mass (3rd digit);
th
An additional grade has been introduced for release force, in relation with safety classification (5 digit);
th
Definition of field of door application has been modified (10 digit);
Safety requirements about Outside Access Device have been added;
Temperature tests have been removed;
Durability tests have been clarified;
Closing test has been changed from dynamic to static.
List of different forces considered in the standard:
F3: Sealing Force;
F9: Static Closing Force;
F10: Dynamic Closing Force;
F11: Release Force under influence of F3;
F13: Security Force;
F14: Abuse Force.

1 Scope
This European Standard specifies requirements, performance and testing of emergency exit devices
mechanically operated by either a lever handle or a push pad for the purpose of achieving a safe exit under an
emergency situation on escape routes.
This European Standard covers emergency exit devices, which are either manufactured and placed on the
market in their entirety by one producer, or assembled from sub-assemblies produced by more than one
producer and subsequently placed on the market as a kit in a single transaction.

3.16
release force
force applied to the operating element, which is necessary to withdraw or release all the bolt head(s) from the
keeper(s), such that a door can be opened
3.17
vertical rod
extension of the bolt head of an emergency exit device that links it to the operating element via the operating
mechanism
3.18
panic exit device
exit device conforming to EN 1125 intended to give safe and effective escape through a doorway with
minimum effort and without prior knowledge of the panic exit device allowing safe escape even in the event of
the door being under pressure such as by people being pushed against the door in the direction of escape
Note 1 to entry: A panic exit device contains bolt head(s) that engage(s) with a keeper(s) in the surrounding door frame
and/or floor for securing a door when closed. The bolt head(s) can be released by the bar positioned horizontally across
the inside face of the door when it is moved anywhere along its effective length in the direction of travel and/or in an arc
downwards.
Note 2 to entry: Panic exit devices are intended for use where panic situations can arise. In a panic situation, a group
of people will react differently from an individual. When two or more people are rushing to an escape door, probably in
darkness and/or smoke, it is possible that the first one to reach the door will not necessarily operate the panic exit device,
but can push the surface of the door (door under pressure) while other people will be trying to operate the horizontal bar
by hand or body pressure.
Note 3 to entry: When a door opens in the direction of exit, a panic exit device can be used instead of an emergency
exit device subject to local regulations.
3.19
emergency exit device
exit device conforming to EN 179 intended for emergency purposes where panic situations are not likely to
arise, to give safe and effective escape through a doorway with one single operation to release the emergency
exit device, although this can require prior knowledge of its operation (see Figures 1, 2 and 3)
Note 1 to entry: An emergency exit device contains bolt head(s) that engage(s) with a keeper(s) in the surrounding
door frame and/or floor for securing a door when closed. The bolt head(s) can be released by the lever handle or the push
pad positioned on the inside face of the door.
Note 2 to entry: Exit devices conforming to EN 179 are intended for emergency purposes where panic situations are
not likely to arise. Where a pressure against the door caused by people in a panic is foreseen, then a panic exit device
conforming to EN 1125 should be used.
Note 3 to entry: Emergency exit devices are suitable also for inwardly opening single leaf exit doors, where local
building regulations allow.

4.2 Ability to release
4.2.1 Design characteristics
4.2.1.1 Lever handle design (Type A)
Lever handle operated emergency exit devices shall be designed to release the door following a movement of
the lever handle in a downward rotational direction.
Lever handles shall be designed to have a minimum length (dimension X) of 120 mm, measured from the axis
of rotation to the free end.
Compliance shall be verified by visual inspection and functional tests
4.2.1.2 Push pad design (Type B)
