European foreword
This document (prEN 15650:2020) has been prepared by Technical Committee CEN/TC 156
“Ventilation for buildings”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 15650:2010.
This document has been prepared under a standardization request given to CEN and CENELEC by the
European Commission and the European Free Trade Association, and supports basic work
requirements of Regulation (EU) 305/2011.
For relationship with EU Regulation, see informative Annex ZA, which is an integral part of this
document.
In addition to a number of editorial revisions, the following main changes have been made with respect
to EN 15650:2010:
— addition of more accurate definitions of fire dampers in Clause 3;
— addition of additional requirements and methodology to assess fire reaction of the product fire
dampers as a whole as an optional performance;
— modification of the drafting of Clause 6 and Annex ZA in accordance with the introduction of AVCP
provisions and the template of Annex ZA agreed at the CEN level.

Introduction
A fire damper is used to prevent fire and reduce smoke spreading through the air ductwork system
which may penetrate fire separating walls and floors. Annex A gives descriptions of typical fire
dampers.
In the case of fire or elevated temperatures, the fire dampers should close automatically by means
contained within their own construction (e.g. a sensing element). As an addition, fire dampers may be
closed by an external signal.
All fire dampers close automatically in response to raised temperatures indicating fire.
Fire dampers can be closed or reset locally at the fire damper or remotely using controls (e.g.
maintenance, testing).
In addition, the aerodynamic performance of fire dampers should be tested in accordance with
EN 1751, if such information is to be presented by a manufacturer.
Example of inspection and maintenance procedure is given in Annex D.

4.5 Resistance to fire
4.5.1 General
The proxy characteristics in 4.5.2 to 4.5.6 shall be taken into account.
These characteristics represent the prime intended use of the fire damper for providing fire resistance
to maintain compartmentation. The fire damper is unviable without them.
Resistance to fire shall be demonstrated by having a minimum value for Integrity of 30 min, or a
combination of Integrity and Insulation of 15 min.
Classification for fire dampers shall be in accordance with EN 13501-3, where specific time
requirements and other parameters are given.
4.5.2 Integrity
Integrity shall be determined using a fire resistance test in accordance with the information and test
methods in 5.4.2 using the largest size of fire damper proposed.
This fire damper shall meet the criteria shown in 5.4.2 that allows it to meet the minimum requirements
for classification E – Integrity.
4.5.3 Insulation
Insulation shall be determined using a fire resistance test in accordance with the information and test
methods in 5.4.3 using the largest size of fire damper proposed.

4.6.1 General
The proxy characteristics in 4.6.2 and 4.6.3 shall be taken into account.
These characteristics are not essentially relevant to the prime intended use of the fire damper for
providing fire resistance to maintain compartmentation, but they do support it for full safety and
security.

4.6.3 Durability of operational reliability
Durability of operational reliability shall be demonstrated by meeting the requirements defined for
operational reliability and the fire damper shall meet at least one of the cycling application categories
shown in 4.4.2.2, 4.4.2.3, 4.4.2.4.
4.7 Reaction to fire (RTF) performance
There are no specific RTF requirements for fire dampers. However, certain countries need reaction to
fire assessment of components used in fire dampers.
Reaction to fire classifications follow the requirements of EN 13501-1.
In general, the main components of fire dampers such as blades and casings meet or exceed a reaction
to fire classification of A2-s1, d0 and only small amounts of material with lower classification are used.
Consequently, if a fire damper gets fire resistance integrity classification E as a minimum, it is deemed
to fulfil all national requirements for reaction to fire performance.
4.8 Construction
4.8.1 Fire dampers
Fire dampers shall have one safety position, which is closed to maintain fire compartments. The reset
position is when the fire damper is open to allow air flow.
Fire dampers shall close under the control of the sensing element, an optional input signal may be used
for early closure.
Consequently, fire dampers shall then:
a) move to and maintain their closed position;
b) have tested leakage characteristics;
c) include a thermal release mechanism that causes the fire damper to close;
d) be fire resistant to maintain fire compartments in closed position.
4.8.2 Actuating mechanisms
Actuating mechanisms shall be constructed and assembled to have the strength and rigidity necessary
to perform the design operations to which they may be subjected, without the loosening or
displacement of parts, or other serious defects when subjected to the tests referred to in Annex C.
Actuating mechanism construction shall be such that it does not cause a fire damper to fail the test by
flaming outside of the furnace and outside the duct.
As smoke is seen as being as, if not more, dangerous than fire, closing actuating mechanisms may be
used that close the fire damper early as the result of, for instance, a fire alarm.
The actuating mechanism shall form a part of the tested fire damper assembly.
The actuating mechanism mounted on the fire damper shall be assessed by an IP42 test as a minimum
in accordance with EN 60529.
4.8.3 Actuators
Actuators may be designed as an integral part of the actuating mechanism or replace it all together. If
the actuator as itself is the actuating mechanism, then it shall be assessed by an IP42 test as a minimum
in accordance with EN 60529.
NOTE Actuators are generally powered in some way, for example electrically or pneumatically.
Actuators shall be constructed and assembled to have the strength and rigidity necessary to perform
the design operations to which they may be subjected, without the loosening or displacement of parts,
or other serious defects when subjected to the tests referred to in Annex C.
Actuator construction shall be such that it does not cause a fire damper to fail the test by flaming
outside of the furnace and outside the duct or collapsing and causing other issues that might cause the
fire damper to fail the fire test.
Where modulating actuators allowing fire dampers to give variable volume control are to be supplied,
these shall be subjected to more extensive cycle testing according to Annex C.
As smoke is seen as being as, if not more, dangerous than fire, actuators may be used that close the fire
damper early as the result of, for instance, a fire alarm.
The actuator shall form a part of the tested construction.
4.8.4 Position indication
When fire dampers incorporate blade positioning signalling devices, such devices shall be
demonstrated to provide information (at ambient temperature) which is indicative of the actual blade
position (open and closed) in accordance with C.1.
4.9 Additional optional characteristics
4.9.1 Protection against corrosion
Where a manufacturer intends to demonstrate an enhanced salt spray corrosion resistant performance
of a fire damper to give a guide on its durability, the test detailed in Annex B shall be performed and the
result of the test declared (i.e. pass/fail). Alternatively, this performance may be made by using of
known-corrosion-resistance products, components and treatments and this shall be declared.
NOTE Except for products used in a corrosive/contaminated environment, there are no corrosion resistance
requirements on products for other uses.
4.9.2 Aerodynamic performance
Where the manufacturer intends to provide information regarding aerodynamic performance, such
performances shall be assessed in accordance with 5.6.2.
5 Test methods
5.1 Nominal activation conditions/sensitivity
5.1.1 Sensing element load bearing capacity
The sensing element shall be tested in accordance with the relevant sections of ISO 21925-1 (formerly
ISO 10294-4).
5.1.2 Sensing element response temperature
The sensing element shall be tested in accordance with the relevant sections of ISO 21925-1 (formerly
ISO 10294-4).
5.2 Response delay (response time to fire)
The closure time shall be assessed during the fire resistance test in accordance with EN 1366-2.
5.3 Operational reliability
The number of cycles shall be assessed in accordance with the methods shown in Annex C.
5.4 Resistance to fire
5.4.1 General
The fire damper and associated actuator shall be tested according to EN 1366-2, installed in the
compartment construction to be used in practice.
Fire dampers shall be fire tested in the plane of proposed installation (i.e. the fire damper shall be
tested horizontally mounted or vertically mounted, depending on the proposed installation).
Fire dampers are generally subjected to an ambient leakage test before the fire test. This is to the
method shown in EN 1366-2 and/or EN 1751.
Tests shall be performed starting with the fire damper in the open position to expose the thermal
release mechanism of the fire damper to furnace conditions, so as to determine the closure time.
NOTE 1 A fire resistance test can be used to assess all of Integrity, Insulation and Smoke Leakage at the same
time, provided that the ambient leakage of the fire damper is recorded prior to the fire resistance test.
NOTE 2 An additional fire resistance test is generally required for each method of installation in each type of
supporting construction, unless covered by direct field of application (DIAP-EN 1366-2) or extended field of
application (EXAP-EN 15882-2).
5.4.2 Integrity
The largest size of fire damper to be produced is tested in accordance with the methods shown in
EN 1366-2.
5.4.3 Insulation

5.6 Additional testing where additional information is to be provided
5.6.1 Protection against corrosion
See Annex B.
5.6.2 Aerodynamic performance
5.6.2.1 General
The following performances and rating test methods for fire dampers and valves specified in EN 1751
and EN ISO 5135 shall be used.
5.6.2.2 Fire damper blade leakage
Leakage past a closed fire damper or valve may be classified using the data published in EN 1751.
5.6.2.3 Fire damper casing leakage
Duct fire damper casings shall be constructed to meet the minimum leakage limits specified for the
ductwork system to which they are installed. Fire dampers shall have casing leakage classes to meet
EN 1751. Ductwork leakage classifications C and D are met by fire dampers having casing leakage
classification C in accordance with EN 1751.
NOTE There is no class D classification for fire damper casings in EN 1751, but due to the small surface area
of a fire damper as part of the whole ductwork system Class C is adequate.
In order to apply the calculation sometimes required to confirm ductwork leakage, the reference casing
area shall be taken as the perimeter size of the fire damper multiplied by the equivalent length of one
metre (e.g. an 800 mm × 400 mm duct fire damper shall have a surface area for casing leakage
performance calculated as ((2 × 0,8) m + (2 × 0,4) m) × 1 m = 2,4 m ).
5.6.2.4 Fire damper flow rate/pressure resistance characteristics
Fire damper flow rate/pressure resistance characteristics shall be measured in accordance with the
method prescribed, and presented in the manner described, in EN 1751.
5.6.2.5 Operational torque testing
Operational torque shall be measured in accordance with the method prescribed, and presented in the
manner described, in EN 1751.
5.6.2.6 Thermal transfer testing
Thermal transfer shall be measured in accordance with the method prescribed, and presented in the
manner described, in EN 1751.
5.6.2.7 Sound radiated to the reverberation room (so called regenerated sound power levels)
The measurement of the sound radiated to the reverberation room by the connecting duct (so
called regenerated sound power levels) shall be measured in accordance with the method
prescribed, and presented in the manner described, in EN ISO 5135.
6 Assessment and verification of constancy of performance - AVCP
6.1 General
The compliance of a fire damper with the requirements of this document and with the performances
declared by the manufacturer in the DoP shall be demonstrated by:
a) determination of the product type;
b) factory production control by the manufacturer, including product assessment.
The manufacturer shall always retain the overall control and shall have the necessary means to take
responsibility for the conformity of the product with its declared performance(s).
Annex G gives an example of declaration of Performance (DoP).
6.2 Type testing
6.2.1 General
All performances related to characteristics included in this document shall be determined when the
manufacturer intends to declare the respective performances unless the standard gives provisions for
declaring them without performing tests. (e.g. use of previously existing data, classified without further
testing (CWFT) and conventionally accepted performance).
Assessment previously performed in accordance with the provisions of this document, may be taken
into account provided that they were made to the same or a more rigorous test method, under the same
AVCP system on the same product or products of similar design, construction and functionality, such
that the results are applicable to the product in question.
NOTE 1 Same AVCP system means testing by an independent third party, under the responsibility of a notified
product certification body.
For the purposes of assessment, the manufacturer's products may be grouped into families, where it is
considered that the results for one or more characte
