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 manual (by hand) 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 3.1.18.
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 leaf doorsets (see 7.10);
— Three specific types of operation:
— emergency exit devices with “lever handle” operation, type A (see 3.1.9 and Figure 1);
— emergency exit devices with “push pad” operation, type B (see 3.1.15 and Figure 2);
— emergency exit devices with “touch pad” operation type C (see 3.1.33 and Figure 3)
— Two categories of emergency exit device projection in order to maximize the effective width of the
escape route, and minimize the projection from the door leaf 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 leaf 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 leaf 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).
NOTE A lock, which is a part of an emergency exit device conforming to this standard can at the same time be
in accordance with EN 1125, EN 12209, prEN 15685, EN 13637, or EN 14846.
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 manufacturer, or assembled from sub-assemblies produced by more
than one manufacturer and subsequently placed on the market as a kit in a single transaction.

4 Product characteristics
4.1 General
The characteristics below are listed according to the essential characteristics of the emergency exit
device.
The numbering of relevant clause of testing each characteristic in 5 corresponds to the one in 4.
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 locking elements of a
door leaf 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.
4.2.1.2 Push pad design (Type B)
Push pad operated emergency exit devices shall be designed to release the locking elements of a door
following a movement in the direction of the door opening in an arc downwards or to the side. This
requirement shall also apply to emergency exit devices intended for use on inwardly opening single leaf
exit doors.
NOTE The term “pull pad” is sometimes used instead of “push pad” for use on inwardly opening single leaf
exit doors.
4.2.1.3 Touch pad design (Type C)
Touch pad operated emergency exit devices shall be designed to release locking elements of a door
following a movement in the direction of the door perpendicular to the face door.
NOTE This type will not be usable for inward opening doors.
4.2.1.4 Exposed edges and corners
An emergency exit device shall have all edges and exposed corners, that are likely to cause injury to
persons using the exit, rounded to a radius of not less than 0,5 mm.
4.2.1.5 Double leaf doorset
The design of an emergency exit device intended for use on double leaf doorset leaves shall allow both
leaves to be opened simultaneously and to swing freely in the direction of exit once the door has been
released.
NOTE 1 The construction and installation of a specific doorset assembly, including choice of hinges, leaf
thickness and leaf width, can have a significant effect on the ability of both leaves to open simultaneously. These
issues are beyond the scope of this European Standard. Additional guidance is given in A.5.
NOTE 2 For example, on rebated double doors, operating the emergency exit device on the inactive leaf will
release both the inactive and the active leaf.
4.2.1.6 Operating element projection
No part of an emergency exit device, when the door is in any position, shall project (dimension W) from
the face of the door more than:
— category 1: projection up to 150 mm (large projection);
— category 2: projection up to 100 mm (standard projection).
NOTE See Figures 4, 5 and 6 for illustration of dimension W (projection).
4.2.1.7 Operating element face
With the emergency exit device secured, the width of the operating element (dimension V) shall be not
less than 18 mm. The shape of the operating element shall facilitate the application of the release force
F11. Verification shall be made in accordance with a) and b). See Figure 7.
a) If the operating element is a lever handle (type A), it shall have on its operating face – to which the
release force is applied – a minimum thickness of 5 mm, either with a flat surface or with a rounded
surface featuring a radius of not less than 0,5 mm. See Figure 7.
b) If the operating element is a push pad (type B) or a touch pad (type C), it shall have an operating
face of not less than 1 400 mm .
For the convenience of more architectural design freedom and less sophisticated production it is
acceptable to allow the lever handle to have a reduced cross-section of not less than 15 mm width
(dimension V) and not less than 4 mm thickness on the operating face, provided this reduction is within
20 mm from the free end of the lever handle.
4.2.1.8 Accessible gap
An emergency exit device shall be designed such that the top surface of any operating element, chassis
or other mounting assembly does not contain any accessible gap that could inadvertently be blocked by
a foreign object, resulting in failure of the emergency exit device to operate.
A test block of 10 mm x 15 mm x 20 mm placed in any accessible gap and in any orientation shall not
prevent correct operation of the emergency exit device.

4.2.1.9 Door free movement
The design of an emergency exit device shall be such that the bolt head(s), once the door has been
released to open, does not restrict or impede the free movement of the door.
The design of an emergency exit device can include a dogging mechanism or an automatic relatching
device. If the exit device is equipped with a dogging mechanism or a device retaining the bolt(s)
retracted, this shall not impede the free movement of the door once released.
An exit device shall be designed to avoid accidental release of the retracted bottom bolt, preventing the
free movement of the door.
4.2.1.10 Top vertical bolt
In order to ensure the self-closing, an emergency exit device with top and bottom vertical rods shall
include a mechanism to ensure that the releasing and/or the manipulation of the bottom vertical rod
bolt head does not release the top vertical rod bolt head. This is verified by pushing the bottom bolt
head up to its flush position with the bolt case.
4.2.1.11 Keepers
The design of an emergency exit device shall include a keeper(s) for protecting the door frame and
engaging the bolt head(s) when the emergency exit device is in the secured position.
Keepers shall provide protection where the door or the frame could be damaged during the opening
and closing cycle of the door
4.2.1.12 Keepers dimensions
The design of a floor keeper shall be such that dust and dirt can easily be removed with a conventional
vacuum cleaner. If the keeper is not fitted flush, then he exposed part of the keeper shall not be upper
than 15mm (dimension H) from the surface to which it is mounted and shall be chamfered in the
direction of escape at an angle (M) not exceeding 45° from the horizontal, and any up stand (dimension
P) shall not exceed 3 mm.
See Figure 8.
Key
H is the height of the floor keeper
M is the angle from the horizontal
P is the up stand of the floor keeper
Figure 8 — Floor keeper dimensions
4.2.1.13 Outside access device
The provision for a connection of an outside access device (key, cylinder, lever handle, knob, etc.) shall
not, in any way, render the emergency exit device inoperable from the inside. The installation
instructions shall clearly indicate the approved configurations for outside access.
An outside access device that is not specified by the manufacturer as designed to be compatible with a
specific emergency exit device shall not be considered to be in conformity with this document.
When an outside access device is intended for use with a thumbturn cylinder, the size and any
positioning of the thumbturn shall not interfere with the operation of the emergency exit device from
the inside.
All the functions of the outside access device which have been declared by the manufacturer of the
emergency exit device shall be verified.
Compliance of all the design characteristics of 4.2.1 above shall be verified by visual inspection and
functional tests carried before the durability test and during final examination in 5.6.7.
The result for characteristics above will be expressed by “Design characteristics checked”.
4.2.2 Release forces
4.2.2.1 Emergency exit devices operated by a lever handle (type A device) or by a touch pad
(type C device)
When an emergency exit device is tested in accordance with 5.2.2.1, the force F11 required to release
the emergency exit device shall not exceed the value declared in 7.5. See Figure 9.
The test result shall be expressed by “grade Y: yyN” according to 7.5.
4.2.2.2 Emergency exit devices operated by a push pad (type B device)
When an emergency exit device is tested in accordance with 5.2.2.2, the force F11 required to release
the emergency exit device shall not exceed the value declared in 7.5. See Figure 9. For “pull pad” type B
emergency exit device, reverse the arrow.
Type A emergency exit device Type B emergency exit device

Type C emergency exit device
Figure 9 — Release forces F11 under influence of F3
If, due to design, the release force F11 can’t be applied at the middle of the push pad, then it shall be
applied at the place where the device is normally operated.
The test result shall be expressed by “grade Y: yyN” according to 7.5.
4.2.3 Release function
An emergency exit device shall be designed to release a door at all times from the inside, by one single
hand operation only, not requiring any other action, e.g the use of a key or other similar object. It shall
be designed to release the door from the time the operating element is operated to the released position
of the mechanism.
The operation of the operating element shall enable immediate release of the locking element(s) from
the inside at all times regardless of any auxiliary locking and/or unlocking means being incorporated,
such as a deadbolt or outside access device.
Compliance shall be verified by 5.2.3.
The test result shall be expressed by “Release function ok”.
4.2.4 Security
When an emergency exit device is tested in accordance with 5.2.4, the device shall remain in the locked
position and shall keep the door closed when subjected to a security force F13 of:
— 1 000 N for attaining grade 2;
— 2 000 N for attaining grade 3;
— 3 000 N for attaining grade 4;
— 5 000 N for attaining grade 5.
Emergency exit devices conforming to this European Standard have a safety rather than a security
function. It is therefore considered essential that the emergency exit device shall continue to be
operable after the application of any security and abuse forces F13 and F14. The test values indicate a
level of strength that shall be achieved without impairing the escape function of the emergency exit
device.
After this test, the release force F11 shall comply with 4.2.2. (to be checked during final examination of
5.6.7)
The test result shall be expressed by “Grade Y: yyN” according to 7.7.
4.3 Suitability for use on fire and smoke resisting doorsets
An emergency exit device intended for use on smoke/fire-resisting doorsets shall meet the following
requirements in accordance with its intended grade described in 7.4.
Grade A: emergency exit devices of Grade A representative of their type shall have been subjected to a
successful evaluation proving their suitability for use on smoke doorsets. For this, all parts of the
emergency exit device that are responsible for keeping the door in its closed position shall be made out
of material with a melting point of not less than 300 °C. If the emergency exit device is equipped with a
latch bolt and the latch bolt could be the only part of the emergency exit device that keeps a smoke
doorset in its closed position, then the projection of the latch bolt shall be at least 10 mm.
NOTE 1 Where the latching of the emergency exit device relies on an emergency exit device to EN 179 or a
panic exit device to EN 1125 classified to Grade A suitability for smoke doors, it can be assumed that the
emergency exit device is meeting this requirement as long as the other elements do not affect the self closing and
latching of the system.
Alternatively, the suitability for use on smoke-resisting doorsets shall be determined by a successful
test conducted in accordance with EN 1634-3.
Installation instructions shall ensure that the engagement of the latch bolt inside the locking plate is not
less than 6 mm.
Grade B: Grade B exit devices representative of their type and including any outside access devices
intended for fire door use shall have been subjected to a successful fire test conducted at least on the
exposed face of the doorset in accordance with EN 1634-1 to prove the contribution of the exit device to
the fire resistance of the complete doorset. It shall not be necessary for the exit device to be operable
after such a fire test.
EN 1634-2 can also be used to extend the field of application for grade B panic exit devices.
NOTE 2 Although the emergency exit devices referred to in this annex are suitable for use with smoke/fire-
resisting doorsets, the safety aspect and ease of escape as described in the introduction to this European Standard
remains of the utmost importance.
Any additional elements installed on the fire test specimen, and which could influence the test result,
shall be clearly identified in the fire test report and shall be included in the product information such
that the limitations to the scope of fire performance approval for the emergency exit device can be
established.
Any additional locking or securing means used on the fire test specimen shall not conflict with the
requirements of Clause 4.
Details of the inclusion or otherwise of a dogging mechanism in the fire test samples shall form a part of
the final fire test report.
Compliance shall be verified by the test methods of EN 1634-1 or EN 1634-2, and EN 1634-3.
Test result shall be expressed by “Grade Y” according to 7.4.
4.4 Self-closing
When an emergency exit device is tested in accordance with 5.4, the dynamic closing force F10 required
to release an automatic relatching device in order to re-engage the emergency exit device in the secured
position shall not exceed 50N.
The test in 5.4 may be omitted if the emergency exit device does not include an automatic re-latching
device.
Test result shall be expressed by “Grade Y” according to 7.3.
4.5 Dangerous substances
National regulations on dangerous substances may require verification and declaration on release, and
sometimes content, when construction products covered by this standard are placed on those markets.
In the absence of European harmonized test methods, verification and declaration on release/content
should be done taking into account national provisions in the place of use.
