Fire resistance test for
door and shutter assemblies - Part 1: Fire doors
and shutters
is needed for material and density
control. Alternative DBI can oversee
the manufacture of the test specimen
in which case no extra specimen is
needed.
General principles
This information sheet describes general principles for determining the
fire resistance of fire doors and shutters.
At DBI it is possible to test two doors
simultaneously if the width of the
doors is less than 1200 mm.
The test specimen is build into a test
frame and placed as front of the
furnace and exposed to standard fire
conditions.
Test specimen
The test specimen shall be fully representative of the door and frame intended for use in practice, including any
surface finishes and fittings which are
an essential part of the specimen and
may influence its behaviour in test.
•
The temperature rise of the thermocouples on the frame exceeds
360 °C.
The average surface temperature is
measured with 5 thermocouples, and
additional with minimum 2 thermocouples on all areas with different
thermal insulation.
On the door leaves the maximum
surface temperature is measured 100
mm from the edges, additional measurements is made 25 mm from the
edges, this is only relevant for a few
countries.
The test specimen shall be full size,
unless the test specimen is bigger
than the opening of the furnace (3 m
x 4.5 m) then it shall be tested to the
maximum size possible.
The maximum surface temperature
is also measured on the frame. An
example of the positioning of thermocouples is shown in figure 1.
The adjustments of the door leaf and
the clearance gabs shall be within the
tolerances of the design values stated
by the sponsor.
Measurement of deflection is a
mandatory requirement to determine
significant movements i.e. greater
than 3 mm (normally the deflection is
measured in 7 places per door leaf).
The tested gabs shall be set between
the middle value and the maximum
of the stated range. The gabs will be
measured prior to the start of the test.
Radiation measurements are recorded
according to EN 1363-2 if the door or
shutter includes glazing.
Besides the doors needed for the
fire resistance test, an extra door
The temperature rise of any of
the thermocouples on the leaves
exceeds 180 °C.
Application of instrumentation
Where compliance with the insulation
criteria (I) is required, thermocouples
shall be attached to the unexposed
face for the purpose of recording the
average and maximum surface temperatures.
The test specimen shall be installed
as in practice, with a choice between
a standard supporting construction
(flexible or rigid) or an associated
construction.
The door or shutter shall be fully operational prior to the test. Normally the
door shall be tested from both sides,
involving two specimens, one from
each direction.
Hinged or pivoted, timber leaf doors
with a timber frame shall only be tested opening into the furnace, if they
are symmetric.
•
Performance criteria
Integrity failure is determined as
described in EN 1363-1, with the exception that the gab gauge must not
be deployed at the cill of the door or
shutter assembly.
Insulation failure is deemed to occur if:
• The temperature rise of the average thermocouples exceeds 140
oC in average.
Radiation failure is deemed to occur if
the radiation measurements exceeds
15 kW/m2.
Field of direct application of
test result
Unless otherwise stated in the following text the construction of door
assembly shall be the same as that
tested. The number of leaves and
the mode of operation (e.g. sliding,
swinging, single action or double
action) shall not be changed.
Specific restrictions on materials
and construction
Timber constructions
• The thickness and density of the
door leaves and timber based panels, shall not be reduced but may
be increased (max. 25% of weight).
•
The cross-sectional dimensions
and/ or the density of the timber
frames (including rebates) shall
not be reduced but may
be increased.
Steel constructions
• The dimensions of steel wrap
around frames may be increased
to accommodate increased supporting construction thickness.
•
The thickness of the steel may
also be increased by up to 25%.
Other variations described in direct of
application are:
The number of stiffening elements for uninsulated doors and
the number and type of fixing of
such members within the panel
fabrication may be increased
proportionally with the increase in
size but shall not be reduced.
•
•
•
Decorative finishes
Paint
Decorative laminates
•
•
Frames
Fixings to the supporting construction may be increased
Glazed constructions
• The type of glass and the edge
fixing technique, including type
and number of fixings per metre
of perimeter, shall not be changed
from those tested.
•
•
The number of glazed apertures
and each of the dimensions of
glass in each pane included within
a test specimen of timber or steel
construction may be decreased
but shall not be increased beyond
the tested.
The distance between the edge of
glazing and the perimeter of the
door leaf or the distance between
glazed apertures shall not be reduced from those incorporated in
the test specimens. Other positioning within the door can only be
modified if this does not involve
the removal or repositioning of
structural members.
Hardware
• Changes in hardware are permitted provided the alternative
hardware has been demonstrated
in another doorset of similar configuration.
•
The number of any movement
restrictors such as locks, latches
and hinges may be increased but
shall not be decreased.
Permissible size variations
• Doors of sizes different from
those of tested specimens are
permitted within certain limitations but the variations are dependent on product type and the
length of time that the performance criteria are fulfilled.
Note of CE marking
The product standards and EN 1634-1
will be used as a basis for CE marking
of fire doors all over EU, however the
product standards relatet to fire have
not yet been released and at present
fire doors can not be CE marked.
