Overview

prEN 15650 - "Ventilation for buildings – Fire dampers" (CEN draft, 2017) defines performance, testing references, and conformity requirements for fire dampers used in building HVAC systems. It covers fire dampers intended to protect compartmentation by closing automatically at elevated temperatures and provides rules for marking, factory production control, and assessment of constancy of performance. Fire dampers certified to this standard are suitable for both ducted and unducted applications and are intended to support fire resistance declarations (Mandate M/117).

Key topics and technical requirements

  • Automatic activation and sensitivity: requirements for thermal activation elements and optional external actuation; declared nominal activation conditions.
  • Response delay (closure time): rules for measuring and declaring how rapidly dampers close when exposed to fire conditions.
  • Operational reliability and durability: lifecycle/cycling tests, maintenance guidance, and requirements to ensure long‑term performance.
  • Resistance to fire: evaluation of integrity, insulation, smoke leakage and mechanical stability when installed in fire separating elements.
  • Smoke leakage and aerodynamics: ambient leakage testing and optional aerodynamic performance data (EN 1751 referenced).
  • Corrosion protection and material reaction to fire: salt spray exposure testing and optional assessment of components’ reaction to fire.
  • Position indication and actuators: requirements for indicating closed/open positions and for actuating mechanisms.
  • Conformity and factory control: Type testing, Factory Production Control (FPC), AVCP procedures, marking, labelling, packaging and an example Declaration of Performance (DoP).

European foreword
This document (prEN 15650:2017) 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 mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive 89/106/EEC.
For relationship with EU Directive, 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 components of fire
dampers as an optional performance;
— modification of the drafting of Clause 6 and Annex ZA in accordance with the required format
related to the Regulation (EU) No 305/2011;
— addition of an example of Declaration of Performance (DoP) in accordance with requirements from
Commission Delegated Regulation (EU) No 574/2014.
Introduction
This document contains the basic performance and requirements for fire dampers.
A fire damper is used to prevent fire and reduce smoke spreading from one fire compartment to
another through the air ductwork system which may penetrate fire separating walls and floors. Annex A
gives descriptions of typical fire dampers.
Where the words “separating element” are used in this document, they should be taken to mean e.g. a
wall, a floor, a ceiling or any other barrier that is designed to maintain compartmentation. This covers
any type of construction (e.g. block and mortar, concrete, board or mineral wool).
In the case of fire or elevated temperatures, the fire dampers should close automatically by means
contained within their own construction (e.g. a thermal activation 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 externally, internally or remotely for maintenance purposes.
Particular reference should be made to EN 1366-2, which defines the furnace testing associated with
fire dampers and EN 13501-3, which provides details on fire resistance classification of fire dampers.
Consideration of any caution notices within any fire testing standards (e.g. health and safety) should be
considered before undertaking any fire 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.
The areas for which products supplied to this document are considered applicable include, but are not
limited to, the following:
a) commercial premises;
b) shopping and retail centres;
c) hospitals;
d) multi-residential buildings.
Example of inspection and maintenance procedure is given in Annex D.
1 Scope
This document applies to fire dampers used in conjunction with fire separating elements to maintain
fire compartments. This document specifies requirements and gives reference to test methods defined
for fire dampers, which are installed in Heating, Ventilating and Air Conditioning (HVAC) installations in
buildings. Details are given for the provision of evaluation of conformity and marking of fire dampers.
To avoid duplication, reference is made to a variety of other standards. To this end, it is advised to read
this document in conjunction with EN 1366-2 for details of the fire resistance testing and EN 13501-3
for classification.
Fire dampers meeting the requirements of this document may be considered suitable for both ducted
and unducted applications.
This document does not consider in detail the detrimental and/or corrosive effects that can be caused
by chemical processes present in the atmosphere, which are drawn through the system intentionally or
inadvertently and therefore does not apply to fire dampers used in such applications. An indication of
salt spray corrosion can be determined using the method described in Annex B.
This document is not applicable to non-mechanical fire barriers nor to air transfer grilles.

4 Requirements
4.1 Nominal activation conditions/sensitivity
4.1.1 General
Fire dampers shall have one safety position, fully closed. This is required to maintain
compartmentation. The reset position is when the fire damper is open to allow air flow.
Fire dampers may be open as part of a heating and ventilating system and shall close only on the receipt
of:
— an elevated temperature; or
— an additional input signal.
Consequently, fire dampers shall:
a) move to and maintain their closed position;
b) have known leakage characteristics;
c) include a thermal release mechanism that causes the fire damper to close (this may be function of
their design), where the thermal release mechanism uses a sensing element which shall be tested in
accordance with 5.2.5;
d) be fire resistant to maintain compartmentation in closed position.
NOTE A facility for manual override to open and close the fire damper for inspection purposes can be useful
and can be included in the product design. This would be of use during commissioning even if no power is
available on site.
4.1.2 Sensitivity
4.1.2.1 Sensing element response temperature
The thermal release mechanism shall be equipped with a sensing element with response temperature
in accordance with test method referred to in 5.2.5.
4.1.2.2 Sensing element load bearing capacity
The thermal release mechanism shall be equipped with a sensing element with load bearing capacity is
in accordance with test method referred to in 5.2.5.
4.1.3 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 unit 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 shall be assessed by an IP42 test as a minimum in accordance with EN 60529.
4.1.4 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. They may be manufactured by the fire damper manufacturer or supplied
by a third party.
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 unit
early as the result of, for instance, a fire alarm.
The actuator shall form a part of the tested construction. Any actuator associated with a fire damper for
everyday use shall be tested at the same time as the fire damper to ensure that it does not cause the fire
damper to fail in any way that may have not been foreseen.
4.1.5 General application
Where the manufacturer intends to provide information regarding aerodynamic characteristics, this
shall be done in accordance with EN 1751.
4.2 Response delay (closure time)
Any temperature may be used; provided that the fire dampers' response delay (closure time) is less
than 2 min in accordance with test method referred to in 5.2.4.

Mechanical stability shall be demonstrated by achieving integrity in accordance with 5.2.2 (see 4.4.2).
4.4.6 Maintenance of cross section
Maintenance of cross section shall be demonstrated by achieving integrity in accordance with 5.2.2 (see
4.4.2).
4.5 Durability
4.5.1 Durability of response delay
Durability of response delay shall be demonstrated by testing the sensing element for response
temperature and load bearing capacity in accordance with 5.2.5.
4.5.2 Durability of operational reliability
Durability of operational reliability shall be demonstrated by application categories in accordance
with 4.3.2.
4.6 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 Annex C, C.1.
4.7 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.
4.8 Aerodynamics performances
Where the manufacturer intends to provide information regarding aerodynamic performances, these
performances shall be assessed following 5.4.
4.9 Reaction to fire (RTF) performance
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 the requirement of reaction to fire performance.
5 Test methods
5.1 Ambient leakage test
The test method shall be in accordance with EN 1366-2 and/or EN 1751.
5.2 Fire resistance test
5.2.1 General
In addition to other requirements in this document, the fire damper shall be subjected to a furnace
mounted fire resistance test. The purpose of this test is to evaluate the ability of a fire damper to
prevent fire and smoke spreading from one fire compartment to another through the air ductwork
system which may penetrate fire separating walls and floors.
The fire damper is attached (directly or remotely via a section of ducting), in/to a supporting
construction (horizontal or vertical mounting) according to a method described in the test standard
EN 1366-2 in a manner generally representative of practice. Fire dampers may be situated:
— within the construction of the wall/floor; or
— attached to the face of the wall/floor; or
— mounted remotely from it via a section of fire resistant ducting.
NOTE Test results are only valid for the tested method of mounting, together with any direct or extended
field of application that can be applicable.
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.
Temperature and integrity measurements shall be carried out in various parts of the test construction
during the test. The impermeability of the fire damper system shall be measured by direct flow
measurements whilst maintaining a constant pressure differential across the closed fire damper of
(300 ± 15) Pa. The leakage rate of fire dampers requiring an S classification shall be measured at
ambient temperature.
It may be necessary to test fire dampers not mounted directly within the centre of the supporting
construction, both inside and outside the supporting construction for it to be universally acceptable for
that method of installation.
5.2.2 Integrity and insulation
For determining fire damper integrity and insulation (if required), the following shall be applied:
— equipment and method as fully described in EN 1366-2;
— the largest size to be manufactured shall be subjected to:
— the opening and closing test; followed by
— the fire resistance test in accordance with EN 1366-2.
Units shall be fire tested in the plane of proposed installation (i.e. for classification the fire
damper shall be tested horizontally mounted or vertically mounted, depending on the
proposed installation).
For information purposes only, the unit may be ambient leakage tested prior to the fire test.
5.2.3 Smoke leakage
For determining the leakage rated fire damper, the following shall be applied:
— equipment and method as fully described in EN 1366-2;
— the largest size to be manufactured shall be subjected to:
— the opening and closing test; followed by
— the ambient leakage test; followed by
— the fire resistance test in accordance with EN 1366-2.
Units need to be fire tested in the plane of proposed installation (i.e. vertically and horizontally).
The smallest size to be manufactured shall be subjected to an ambient leakage test in accordance with
5.4
5.2.4 Response delay
To determine response delay of a fire damper, any temperature may be used, provided that the units
demonstrate closure within the time period defined in EN 1366-2.
5.2.5 Sensing element
5.2.5.1 Response temperature
The thermal release mechanism uses a sensing element that responds to an increase in temperature
shall be in accordance with ISO 10294-4.
5.2.5.2 Load bearing capacity
The thermal release mechanism uses a sensing element which load bearing capacity shall be in
accordance with the relevant sections of ISO 10294-4.
5.3 Salt spray exposure test
The equipment and test method referenced in Annex B and EN 60068-2-52 shall be used for salt spray
exposure test.
5.4 Fire damper aerodynamic performance
The following performance and rating test methods for fire dampers and valves specified in EN 1751
and EN ISO 5135 shall be used:
a) fire damper blade leakage;
Leakage past a closed fire damper or valve may be classified using the data published in EN 1751.
Classes then increase 1 to 4 with class 4 being the most leak tight;
b) 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 ).
c) 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.
d) operational torque testing;
Operational torque shall be measured in accordance with the method prescribed, and presented in
the manner described, in EN 1751.
e) thermal transfer testing;
Thermal transfer shall be measured in accordance with the method prescribed, and presented in
the manner described, in EN 1751.
f) regenerated sound power levels;
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 standard 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 standard 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 standard, 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 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 characteristics from any one product within the family are
representative for those same characteristics for all products within that same family.
Products may be grouped in different families for different characteristics.
Reference to the assessment method standards should be made to allow the selection of a suitable
representative sample.
In addition, the determination of the product type shall be performed for all characteristics included in
the standard for which the manufacturer declares the performance:
— at the beginning of the production of a new or modified fire damper (unless a member of the same
product range), or
— at the beginning of a new or modified method of production (where this may affect the stated
properties); or
they shall be repeated for the appropriate characteristic(s), whenever a change occurs in the fire
damper design, in the raw material or in the supplier of the components, or in the method of production
(subject to the definition of a family), which would affect significantly one or more of the characteristics.
Where components are used whose characteristics have already been determined, by the component
manufacturer, on the basis of assessment methods of other product standards, these characteristics
need not be re-assessed. The specifications of these components shall be documented.
Products bearing regulatory marking in accordance with appropriate harmonized European
specifications may be presumed to have the performances declared in the DoP, although this does not
replace the responsibility on the fire damper manufacturer to ensure that the fire damper as a whole is
correctly manufactured and its component products have the declared performance values.
6.2.2 Test samples, testing and compliance criteria
The number of samples of fire dampers to be tested/assessed shall be in accordance with Table 1.
