Foreword
This document (prEN 15882-2:2010) has been prepared by Technical Committee CEN/TC 127 “Fire
safety in buildings”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
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 89\106\EEC.
Introduction
It should be noted that fire-resisting dampers are special products that are exposed to different
conditions to other elements of construction; in particular they are subjected to significantly different
pressure regimes. Also integrity is evaluated by leakage measurements. Consequently, this European
standard may adopt a different approach to other extended field of application standards, with more
emphasis on testing.

1 Scope
This standard provides guidance and rules to notified or accredited bodies (for Fire Dampers) to allow
them to define the extended field of application for fire dampers. This standard 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.
The standard gives 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.
The standard does not cover dampers used for smoke control.
This document only applies to extended fields of application based on tests successfully undertaken
to EN 1366-2. Leakage determined during such tests shall be at least 10 % below the leakage limits
for E, or for ES, dependent on classification achieved, given in EN 13501-3 before the EXAP rules
can be applied.
By application of this standard, it should be possible to identify what specifications should be tested to
maximise the field of application. Some information on test programmes is given for guidance
purposes.

4 Determination of worst case
In certain circumstances a rule may call for a new test to be undertaken. To save having to re-test
everything, a determination must be made of “worst case”.
Firstly consider the classification required: E, EI, ES, EIS, Consider all the test reports that give the
required classification.
Only test reports that have a total test time that is in excess of the required classification period by a
of either 10% or 12 minutes, whichever is the least, may be considered.
Determine which criteria failed first in each test. The resulting “worst case” will be the one where the
time to failure of each and any of the parameters was the lowest.
If the test periods show that none of the criteria failed before the classification period plus 10% or 12
minutes, then the supporting construction must be considered. The worst case will be with the fire
damper mounted in the lightest construction. The sponsor may pick a heavier supporting construction,
but then any extended field of applications will only apply to this supporting construction and those
heavier and more dense as per direct field of application.
The method of determination of worst case and the related extended fields of application shall be
reported in the extended field of application report

5 Conditions and application rules
5.1 Change of fixing damper to supporting construction
a) No change in the location of the fixings relative to the damper and the supporting construction
shall be permitted. The pitch between the fixings shall not be increased
b) Alternative fixings may be used if their performance is proven by supporting data, including, but
not necessarily limited to fire test and loading information.
c) Any alternative fixings shall be included as part of the extended field of application report
5.2 Multiple damper assemblies
To allow the use of multiple assemblies of fire dampers, either side by side or on top of each other, a
test shall be undertaken. An assembly consisting of fire dampers that have already successfully
gained a classification to EN13501-3 shall be made and installed into a supporting construction using
the proposed method.
A fire damper selected using the worst case method described above shall be made into an assembly
as shown below. This will allow the other EXAP rules from the tables which follow to apply to multi-
section units, as they do to single section units.
The unit to be tested shall be constructed so as to be made up of at least four sections and shall have
a maximum overall size of 2600mm x 2600mm. This is to allow for a small gap around the outside of
the damper and a minimum span of supporting construction of 300mm all round.
The test method will be generally as EN1366-2 (note: also refer to intumescent fire damper test, if this
becomes relevant), but instead of a closed plenum with a fan, an extended open duct 1m long shall
be fixed to the dampers. This will allow the placing of the thermocouples described in EN1366-2 to be
fixed in their normal positions.
Leakage will not be measured. A 300Pa differential pressure will not be set across the unit. The
criteria used will be the integrity round the joint between the damper installation and the supporting
construction, sustained flaming at any point, and the insulation criteria on the outside of the duct
section.
NOTE The above was decided, because equipment may not be readily available at laboratories to allow the
pressure differential and required volumes to be set up.
Classification will be as the original single section units with regard to E, EI, ES and EIS as long as
the above integrity criteria are fulfilled and any insulation criteria are met.
If, due to the size restriction of 2600 x 2600, the assembly is made up of four individual units which
are smaller, or of the same, size as the original single unit tested, assemblies for application may be
made of units up to the single unit size tested:
e.g. an assembly of four units with an overall size of 2600mm x 2600mm, made from individual
units with overall size 1300 x1300, representing a single section size tested of 1500 x 1300,
allows an assembly of overall size 3000 x 2600 to be used.
If the assembly is made up of four or more units, leading to whatever overall size, the size of unit to be
used must have been tested previously as a single unit. For application, the units then used to make
up assemblies must not exceed the size of the units tested as part of the assembly. This test may not
be used to allow larger units to be back assessed to single sections for classification to EN13501-3:
e.g. an assembly of 6 units individual overall size 600 x 600, giving an assembly 1200 x 1800,
allows the use of multiple assemblies of units of individual size 600 x 600.

---------------------- Page: 8 ----------------------
oSIST prEN 15882-2:2011
prEN 15882-2:2010 (E)
If the individual unit tested was 1000 x 1000, the use of this to build assemblies is not now
allowed as this could have been assembled to form a unit 2000 x 2000, which could be tested
(i.e. is less than 2600 x 2600).
If the 600 x 600 size has not been tested individually and only a 500 x 500 unit has been tested
previously, this is not allowed and back assessment of the 500 x500 is also not allowed as there
is no pressure differential in this EXAP test.
For dampers tested following these directions, the standard direct field of application from EN1366-2
shall apply.
All details with respect to multiple damper assemblies, and their associated testing, and any direct
field of application and further EXAP, shall be included in the extended application report
Using the information gained above, larger assemblies of individual dampers are allowed, providing
that they are also structurally supported to a fire-safe design provided by structural fire engineers.
See Figure 1
5.3 Alternative penetration seals
Alternative penetration seals shall be tested in association with a fire damper in accordance with
EN1366-2.
Alternatively, penetration seals with a density and application method similar to one already tested
with the specific fire damper may be used, provided that they (the penetration seal) have successfully
passed a test in accordance with EN 1366-3
All details of alternative penetration seals shall be included in the extended field of application report.
6 Influence of parameters and factors on fire damper performance
This standard takes into account the parameters and factors that may affect the fire resistance
performance of fire resisting dampers when tested to the method of test defined in EN 1366-2. These
have been listed in the following tables
The influence on integrity, insulation and where appropriate smoke leakage, shall be appraised in
accordance with the clauses and tables in this standard. .
The parameters and factors of the anticipated influence on damper performance are given in the
tables of clause 7.
Consideration of the parameters and factors in clause 7 have lead to the development of the rules in
clause 8, which state what conclusions may be drawn or the requirement for further testing, whichever
is relevant.
