Introduction
It should be noted that fire resisting dampers are special products that are exposed to different conditions
than other elements of construction; in particular they are subjected to significantly different pressure
regimes. Integrity is also evaluated through leakage measurements. Consequently, this document may
adopt a different approach to other extended field of application standards, with more emphasis on
testing.
Some rule references and content have changed from the previous version of this document and some
conclusions to the previous version may not be acceptable in the light of this new information.

1 Scope
This document provides guidance and rules to notified bodies (for fire dampers) allowing them to
produce/validate an extended field of application report for fire dampers based on testing undertaken in
accordance with EN 1366-2. This document identifies the parameters that affect the fire resistance of fire
dampers. It also identifies the factors that need to be considered when deciding whether, or by how much,
the parameter can be extended when contemplating the fire resistance performance of an untested, or
untestable variation in the construction.
This document explains the principles behind how a conclusion on the influence of specific
parameters/constructional details relating to the relevant criteria (E, I, S) can be achieved.
This document does not cover dampers used for smoke control or non-mechanical fire barriers.
It is the intention that the application of this document makes it possible to identify which specifications
to test to maximize the field of application. Some information on test programmes is given for guidance
purposes.

4 Test requirements for assessment of design changes and modification of the
manufacturing process
4.1 General
Many manufacturers will want to introduce manufacturing changes to make use of differing production
techniques, whilst essentially keeping a product the same. In addition, they may wish, for example, to
change actuators and activating mechanisms, sometimes across a range of product models.
The test methods described in the following subclauses shall not be used to develop the application to
other supporting constructions and installation methods in those supporting constructions.
4.2 Design and manufacturing changes
4.2.1 Pre-test
Before any fire testing is undertaken the relevant cycle tests and leakage tests at ambient temperatures
shall be undertaken to prove the durability of the proposed change in accordance with EN 15650.
7
---------------------- Page: 9 ----------------------
SIST EN 15882-2:2022
EN 15882-2:2022 (E)
4.2.2 Fire test
The effect of design and manufacturing changes on the declared performances of essential characteristics
of the fire damper shall be proven by fire testing the fire damper in a previously tested supporting
construction and using the same installation method.
The supporting construction shall be the lightest in terms of mechanical stability that the fire damper was
previously tested in (e.g. dry wall versus solid masonry etc.). The fire damper shall be presented to the
test from the direction of the worst result obtained in previous testing or, if this is not clear from previous
test evidence, then with the actuator inside the furnace.
4.2.3 Extended field of application
Having passed the fire test in 4.2.2, the fire damper shall have the ability to be used for all other existing
classifications with an equal or lower classification time for the same supporting construction using any
already tested installation methods.
This is also allowed for all its other existing models with classifications with equal or lower classification
times in heavier supporting constructions with their different installation methods in accordance with
the existing direct field of application.
4.3 Actuators, remote triggering devices, actuating mechanisms, fusible links and
sensing elements
4.3.1 Actuators
4.3.1.1 General
If the fire damper assembly is a new design, previously untested, this section does not apply, and the fire
damper shall be tested fitted with the actuator in accordance with EN 1366-2 from both sides.
If the fire damper assembly has not been previously tested from both sides using an actuator/mechanism
etc, then this section does not apply until the fire damper assembly has been tested with the actuator in
accordance with EN 1366-2 from both sides.
When either of the above have been successfully tested the following may be applied.
All the following shall be undertaken in the order shown.
Actuator models with different voltages (e.g. 24 V, 230 V or multi-voltage) are considered to have no
influence on fire safety. Just one voltage needs to be tested. In the case of multi-voltage any voltage may
be tested.
4.3.1.2 Fire damper ambient cycle test
At least one sample of the fire damper assembly with the proposed new actuator shall be subjected to an
ambient cycle test.
The minimum number of cycles performed shall correspond to the expected application as shown in
EN 15650.
If different motive powers are proposed, then an actuator with each motive power level shall be subjected
to the cycle tests.
4.3.1.3 Confirmatory acceptance fire test
At least one sample (different to those in 4.3.1.2) of the proposed new actuator shall be subjected to a fire
test in accordance with EN 1366-2 on a previously tested fire damper obtained from the fire damper
manufacturer, installed in the lightest wall construction (generally lightweight metal stud partition with
one board on each side as the worst case).
8
---------------------- Page: 10 ----------------------
SIST EN 15882-2:2022
EN 15882-2:2022 (E)
In cases of insulated fire dampers (with an EI classification), the actuator shall be positioned inside the
furnace. With only E classification dampers, two units shall be tested; one mounted on an E classification
fire damper inside the furnace and one mounted on an E classification fire damper outside the furnace.
Successful completion of a fire test on E classification fire dampers will allow use on EI classification fire
dampers.
To avoid confusion, even if the fire damper has the actuator mounted on the centre line, the product shall
be tested from both sides in the case of E or EI classification dampers.
In each case the fire damper shall perform at least as well, with regard to its classification times, as it did
in the same test previously. Tests performed on a vertically mounted fire damper will be applicable to
horizontally mounted fire dampers and vice versa.
4.3.1.4 Field of application
Provided all the above are fulfilled in order, the actuator may be fitted by the fire damper manufacturer
on tested families and series of fire damper. This shall apply to all tested installations and applications.
4.3.2 Actuators with an associated thermal element device that controls the action of the
actuator to close the fire damper in the event of fire
4.3.2.1 General
If the fire damper assembly is a new design, not previously tested, this section does not apply, and the
fire damper shall be tested fitted with the associated actuator in accordance with EN 1366-2 from both
sides.
If the fire damper assembly has not been previously tested from both sides using an actuator with
associated thermal element device then this section does not apply until the fire damper assembly has
been tested with the associated actuator in accordance with EN 1366-2 from both sides.
When either of the above have been successfully tested, the following may be applied.
All the following shall be undertaken in the order shown.
Actuator models with different voltages (e.g. 24 V, 230 V or multi-voltage) are considered to have no
influence on fire safety. Just one voltage needs to be tested. In the case of multi-voltage any voltage may
be tested.
4.3.2.2 Fire damper ambient cycle test
As in 4.3.1.2.
4.3.2.3 Confirmation of the thermal element device
The thermal element device shall pass the requirements of ISO 21925-1 (previously in ISO 10294-4 as
originally referenced in EN 15650).
4.3.2.4 Confirmatory acceptance fire test
As in 4.3.1.3.
If only the design of a thermal element device has been changed, conformity with 4.3.1.2 shall be fulfilled
without additional fire testing.
4.3.2.5 Field of application
Provided all the above are fulfilled in order, the actuator with the thermal element device may be fitted
by the fire damper manufacturer on tested families and series of fire damper. This shall apply to all tested
installations and applications.

4.3.3 Remote triggering device (e.g. magnet)
4.3.3.1 General
In all cases fire dampers must have a thermal element device. This section covers any additional remote
mechanical triggering device.
If the fire damper is a new product, not previously tested, this section does not apply, and the fire damper
shall be tested fitted with an associated remote triggering device in accordance with EN 1366-2, from
both sides.
If the fire damper has not been previously tested from both sides using an associated remote triggering
device, then this section does not apply until the fire damper has been tested in accordance with
EN 1366-2 from both sides.
When either of the above have been successfully tested the following may be applied.
All the following shall be undertaken in the order shown.
4.3.3.2 Fire damper ambient cycle test
At least one sample of the fire damper assembly with the proposed new remote triggering device shall be
subjected to an ambient cycle test.
The minimum number of cycles performed shall correspond to the expected application as shown in
EN 15650.
4.3.3.3 Confirmatory acceptance fire test
At least two samples (different from 4.3.3.2) of the fire damper with the proposed new remote triggering
device shall be subjected to a fire test in accordance with EN 1366-2 on a previously tested fire damper
obtained from the fire damper manufacturer in the lightest wall construction (generally lightweight metal
stud partition with one board on each side as the worst case).
Two units shall be tested; one with new remote triggering device mounted inside the furnace and one
with the new remote triggering device mounted outside the furnace.
To avoid confusion, even if the fire damper has the new remote triggering device mounted on the centre
line, the product shall still be tested from both sides.
In each case the fire damper shall perform at least as well as it did in the same test previously. Tests
performed on a vertically mounted fire damper will be applicable to horizontally mounted fire dampers
and vice versa.
4.3.3.4 Field of application
Provided all the above are fulfilled in order, the new remote triggering device may be fitted by the fire
damper manufacturer on tested families and series of fire damper. This shall apply to all tested
installations and applications.
4.3.4 Actuating mechanism
4.3.4.1 General
The actuating mechanism is the connection mechanism between the actuator and/or remote release
mechanism and the damper blade. Modification may be made for different reasons (e.g. to simplify the
construction or change mechanical advantage).
If the fire damper assembly is a new product, previously untested, this section does not apply, and the
fire damper assembly shall be tested in accordance with EN 1366-2 from both sides.

---------------------- Page: 12 ----------------------
SIST EN 15882-2:2022
EN 15882-2:2022 (E)
If the fire damper assembly has not been previously tested from both sides, then this section does not
apply until the fire damper assembly has been tested in accordance with EN 1366-2 from both sides.
When either of the above have been successfully tested the following may be applied.
All the following shall be undertaken in the order shown.
4.3.4.2 Fire damper ambient cycle test
At least one sample of the fire damper assembly with the proposed new actuating mechanism shall be
subjected to an ambient cycle test in each orientation proposed (e.g. horizontal and/or vertical).
The minimum number of cycles performed shall correspond to the expected application as shown in
EN 15650.
The mechanical advantage shall not be reduced.
If the previous actuating mechanism to be replaced does not have this data available for comparison then
the previous actuating mechanism shall be tested in this way at the same time as the proposed new
actuating mechanism to maintain consistency of testing.
4.3.4.3 Confirmatory acceptance fire test
At least two samples (different to those used 4.3.4.2 above) of the fire damper with the proposed new
actuating mechanism shall be subjected to a fire test in accordance with EN 1366-2, on a previously tested
fire damper in the lightest wall construction (generally lightweight metal stud partition with one board
on each side).
The actuator shall be mounted such that if the fastenings or pins preventing rotation fail, the weight of
the damper shall act to try and open the blades by putting an opening moment on the drive spindle to the
actuating mechanism.
Two units shall be tested, one with the actuating mechanism mounted inside the furnace and one with
the actuating mechanism mounted outside the furnace.
To avoid confusion, if the fire damper has the actuating mechanism mounted on the centre line, the
product shall still be tested from both sides.
In each case the fire damper shall perform at least as well as it did in the same test previously. Tests
performed on a vertically mounted fire damper will be applicable to horizontally mounted fire dampers
and vice versa.
4.3.4.4 Field of application
Provided all the above are fulfilled in order, the actuating mechanism may be fitted to any smaller fire
damper of the same type/family with the same or lower nominal declared torque on all the
manufacturers tested families and series of fire damper. This shall apply to all tested installations and
applications.
4.3.5 Fusible links and elements (not associated with the actuator supplier)
4.3.5.1 General
If the fire damper assembly is a new product, previously untested, this section does not apply, and the
fire damper assembly shall be tested in accordance with EN 1366-2 from both sides.
If the fire damper assembly has not been previously tested from both sides, then this section does not
apply until the fire damper assembly has been tested with the associated fusible link and element in
accordance with EN 1366-2 from both sides.
When either of the above have been successfully tested, the following may be applied.

Introduction
It should be noted that fire resisting dampers are special products that are exposed to different conditions
than other elements of construction; in particular they are subjected to significantly different pressure
regimes. Integrity is also evaluated through leakage measurements. Consequently, this document may
adopt a different approach to other extended field of application standards, with more emphasis on
testing.

1 Scope
This document provides guidance and rules to notified bodies (for fire dampers) allowing them to
produce/validate an extended field of application report for fire dampers. This document identifies the
parameters that affect the fire resistance of dampers. It also identifies the factors that need to be
considered when deciding whether, or by how much, the parameter can be extended when contemplating
the fire resistance performance of an untested, or untestable variation in the construction.
This document explains the principles behind how a conclusion on the influence of specific
parameters/constructional details relating to the relevant criteria (E, I, S) can be achieved.
This document does not cover dampers used for smoke control.
It is the intention that the application of this document makes it possible to identify which specifications
to test to maximize the field of application. Some information on test programmes is given for guidance
purposes.

4 Test requirements for assessment of design changes
4.1 General
Many manufacturers will want to introduce manufacturing changes to make use of differing production
techniques, whilst essentially keeping a product the same. In addition, they may wish to change actuators
and activating mechanisms, sometimes across a range of products.
Such a test shall not be used to develop the application to other supporting constructions and installation
methods in those supporting constructions.
4.2 Manufacturing changes
4.2.1 Pre-test
Before any fire testing is undertaken the relevant cycle tests and leakage tests at ambient temperatures
shall be undertaken to prove the durability of the proposed change.
4.2.2 Fire test
Manufacturing changes shall be proven by fire testing the fire damper in previously tested supporting
construction and using the same installation method. The supporting construction shall be the lightest
that the fire damper was previously tested in (e.g. dry wall versus solid masonry etc.). The fire damper
shall be presented to the test from the direction of the worst result obtained in previous testing or, if this
is not clear from previous test evidence, then with the actuator inside the furnace.
4.2.3 Extended field of application
The fire damper shall have the ability to be used for all other existing classifications for the same
supporting construction using different installation methods and also all for all its existing classifications
in heavier supporting constructions with their different installation methods.

4.3 Actuators, remote triggering devices, actuating mechanisms, fusible links and
sensing elements
4.3.1 Actuators
4.3.1.1 General
This only applies to new ranges of actuator provided by the same actuator manufacturer.
If the fire damper is a new product, previously untested, this section does not apply, and the fire damper
shall be tested fitted with the actuator associated with EN 1366-2 from both sides.
If the fire damper has not been previously tested from both sides using an actuator, then this section does
not apply until the fire damper has been tested with the actuator associated with EN 1366-2 from both
sides.
When either of the above have been successfully tested the following may be applied.
All the following shall be undertaken in the order shown.
4.3.1.2 Actuator ambient cycle test under load
At least one sample of the proposed new actuator shall be subjected to an ambient cycle test under load
in both directions of rotation by the actuator manufacturer. The actuator will not be connected to a fire
damper for this test. The load applied shall be at least the nominal declared load in accordance with the
actuator specification and shall be set by the actuator manufacturer. The minimum number of cycles
performed shall correspond to the expected application. This shall be 10 200 for general purpose fire
damper actuators and 20 000 for modulating fire dampers. If different motive powers are proposed, then
an actuator with each motive power level shall be subjected to the cycle tests.
The ambient spring return running time shall be the same or shorter than the actuator being replaced.
The ambient spring return torque shall be the same or greater than the actuator being replaced.
The ambient angle of rotation shall be the same as the actuator being replaced.
The calorific value of any combustible material in the actuator construction shall be the same or less than
the actuator being replaced.
If the actuator range (from the same manufacturer) of the actuator being replaced does not have this data
available for comparison it shall be tested in this way at the same time as the proposed new actuator.
4.3.1.3 Actuator fire test
At least one sample (different from that in 4.3.1.2) of the proposed new actuator shall be subjected to a
fire test under load by the actuator manufacturer. The load to be used shall be set by the actuator
manufacturer and shall be at least the nominal declared load corresponding to 4.3.1.2.
The actuator shall perform 50 cycles at ambient prior to the fire test under nominal declared load
specified by actuators manufacturer.
The actuator shall be mounted on the inside of the furnace with the loading arranged on the outside of
the furnace.
The actuator shall be subjected to a fire test following the general fire test parameters of EN 1366-2.
The actuator shall be powered to the ON (open) position before the test is started and released to the OFF
(closed) position by removing the supply power when furnace reaches 50°C. The actuator shall reach the
OFF (closed) position in less than two minutes.
The actuator shall maintain its position for the same time or longer than the actuator being replaced.

If the actuator range (from the same manufacturer) of the actuator being replaced does not have this data
available for comparison it shall be tested in this way at the same time as the proposed new actuator.
4.3.1.4 Confirmatory acceptance fire test
At least one sample (different to those in 4.3.1.2 and 4.3.1.3) of the proposed new actuator shall be
subjected to a fire test in accordance with EN 1366-2 on a previously tested fire damper obtained from
any fire damper manufacturer, installed in the lightest wall construction (generally lightweight metal
stud partition with one board on each side as the worst case).
In cases of insulated fire dampers (with an EI classification), the actuator shall be positioned inside the
furnace. With only E classification dampers, two units shall be tested; one mounted on an E classification
fire damper inside the furnace and one mounted on an E classification fire damper outside the furnace.
Successful completion of a fire test on E classification fire dampers will allow use on EI classification fire
dampers.
To avoid confusion, even if the fire damper has the actuator mounted on the centre line, the product shall
be tested from both sides in the case of E or EI classification dampers.
In each case the fire damper shall perform at least as well, with regard to its classification times, as it did
in the same test previously. Tests performed on a vertically mounted fire damper will be applicable to
horizontally mounted fire dampers and vice versa.
4.3.1.5 Field of application
Provided all the above are satisfactorily fulfilled in order, the actuator may be supplied to and fitted by
any fire damper manufacturer who has previously fitted a similar actuator from the same actuator
manufacturer on tested families and series of fire damper. This shall apply to all tested installations and
applications.
4.3.2 Actuators with an associated thermal element device that controls the action of the
actuator to close the fire damper in the event of fire
4.3.2.1 General
This only applies to new ranges of actuator provided by the same actuator manufacturer
If the fire damper is a new product, not previously tested, this section does not apply, and the fire damper
shall be tested fitted with the associated actuator in accordance with EN 1366-2 from both sides.
If the fire damper has not been previously tested from both sides using an actuator with associated
thermal element device then this section does not apply until the fire damper has been tested with the
associated actuator in accordance with EN 1366-2 from both sides.
When either of the above have been successfully tested, the following may be applied.
All the following shall be undertaken in the order shown.
4.3.2.2 Actuator ambient cycle test under load
As in 4.3.1.2.
4.3.2.3 Actuator fire test
As in 4.3.1.2.

4.3.2.5 Confirmatory acceptance fire test
As in 4.3.1.3.
If only the design or type of a thermal element device has been changed, conformity with 4.3.1.2 shall be
fulfilled without additional fire testing.
4.3.2.6 Field of application
Provided all the above are satisfactorily fulfilled in order, the actuator with the thermal element device
may be supplied to and fitted by any fire damper manufacturer who has previously fitted a similar
actuator with a thermal element device from the same actuator manufacturer on tested families and
series of fire damper. This shall apply to all tested installations and applications.
4.3.3 Remote triggering device (e.g. magnet)
4.3.3.1 General
If the fire damper is a new product, not previously tested, this section does not apply, and the fire damper
shall be tested fitted with an associated remote triggering device in accordance with EN 1366-2, from
both sides.
If the fire damper has not been previously tested from both sides using an associated remote triggering
device, then this section does not apply until the fire damper has been tested in accordance with EN 1366-
2 from both sides.
When either of the above have been successfully tested the following may be applied.
All the following shall be undertaken in the order shown.
4.3.3.2 Damper ambient cycle test
At least one sample of the fire damper with the proposed new remote triggering device shall be subjected
to an ambient cycle test under load. The cycles performed shall be at minimum corresponding to the
expected application. The minimum number of cycles performed shall correspond to the expected
application: This shall be at least 300 cycles (10 200 or 20 000 may be selected). If different motive
powers are proposed, then a remote triggering mechanism with each motive power level shall be
subjected to the cycle tests.
4.3.3.3 Confirmatory acceptance fire test
At least two samples (different from 4.3.1.2) of the proposed new remote triggering device shall be
subjected to a fire test in accordance with EN 1366-2 on a previously tested fire damper obtained from
any fire damper manufacturer in the lightest wall construction (generally lightweight metal stud partition
with one board on each side / worst case).
Two units shall be tested; one with new remote triggering device mounted inside the furnace and one
with the new remote triggering device mounted outside the furnace.
To avoid confusion, even if the fire damper has the new remote triggering device mounted on the centre
line, the product shall still be tested from both sides.
In each case the fire damper shall perform at least as well as it did in the same test previously. Tests
performed on a vertically mounted fire damper will be applicable to horizontally mounted fire dampers
and vice versa.

apply to all tested installations and applications.
4.3.4 Actuating mechanism
4.3.4.1 General
The actuating mechanism is the connection mechanism between any actuator or remote release
mechanism and the damper blade. Modification may be made for different reasons (e.g. to simplify the
construction or change mechanical advantage).
If the fire damper is a new product, previously untested, this section does not apply, and the fire damper
shall be tested in accordance with EN 1366-2 from both sides.
If the fire damper has not been previously tested from both sides, then this section does not apply until
the fire damper has been tested in accordance with EN 1366-2 from both sides.
When either of the above have been successfully tested the following may be applied.
All the following shall be undertaken in the order shown.
4.3.4.2 Damper ambient cycle test
At least one sample of the fire damper with the proposed new actuating mechanism shall be subjected to
an ambient cycle test.
The minimum number of cycles performed shall correspond to the expected application. This shall be
300 for remote release only, 10 200 for general purpose fire damper actuators and 20 000 for modulating
fire dampers.
The mechanical advantage shall not be reduced.
If the previous actuating mechanism to be replaced does not have this data available for comparison it
shall be tested in this way at the same time as the proposed new actuator.
4.3.4.3 Confirmatory acceptance fire test
At least two samples (different to those used above) of the fire damper with the proposed new actuating
mechanism shall be subjected to a fire test in accordance with EN 1366-2, on a previously tested fire
damper in the lightest wall construction (generally lightweight metal stud partition with one board on
each side).
The actuator shall be mounted such that if the fastenings or pins preventing rotation fail, the weight of
the damper shall act to try and open the blades by putting an opening moment on the drive spindle to the
actuating mechanism.
Two units shall be tested, one with the actuating mechanism mounted inside the furnace and one with
the actuating mechanism mounted outside the furnace.
To avoid confusion, if the fire damper has the actuating mechanism mounted on the centre line, the
product shall still be tested from both sides.
In each case the fire damper shall perform at least as well as it did in the same test previously. Tests
performed on a vertically mounted fire damper will be applicable to horizontally mounted fire dampers
and vice versa.
4.3.4.4 Field of application
Provided all the above are satisfactorily fulfilled in order, the actuating mechanism may be fitted to any
smaller fire damper with the same or lower nominal declared torque on all the manufacturers tested
families and series of fire damper. This shall apply to all tested installations and applications.
