Fire resistance tests —
Part 3:
Door and shutter assemblies horizontally oriented
CAUTION — The attention of all persons concerned with managing and carrying out this
fire-resistance test is drawn to the fact that fire testing may be hazardous and that there is a
possibility that toxic and/or harmful smoke and gases may be evolved during the test. Mechanical
and operational hazards may also arise during the construction of test elements or structures,
their testing and disposal of test residues.
An assessment of all potential hazards and health risks shall be made by the laboratory and safety
precautions shall be identified and provided. Written safety instructions shall be issued. Appropriate
training shall be given to relevant personnel. Laboratory personnel shall ensure that they follow written
safety instructions at all times.
1 Scope

and the following apply.
3.1
associated supporting construction
specific construction in which the door or shutter assembly is installed as intended for use in practice
and which is used to close off the furnace and provide the levels of restraint and thermal heat transfer
to be experienced in normal use
© ISO 2016 – All rights reserved 1
---------------------- Page: 7 ----------------------
ISO 3008-3:2016(E)
3.2
door assembly
combination of a door, a frame, hardware, closers, sealing materials and other accessories installed in a
horizontal plane, which together provide a specific degree of fire-resistance to a through opening in a
fire-resistance rated floor or roof
3.3
shutter assembly
complete assembly consisting of rolling, folded or sliding panels or slats including guides, rollers, tracks,
other accessories, operating mechanism and housings intended for installation in a horizontal plane
3.4
standard supporting construction
form of construction used to close off the furnace and to support the door assembly being evaluated
and has a quantifiable influence on both the thermal heat transfer between the construction and the
test specimen and provides known resistance to thermal distortion
3.5
door length
direction of the door panel, door assembly or shutter which has the greatest dimension
3.6
door width
direction of the door panel, door assembly or shutter which has the shortest dimension
4 Test equipment
4.1 The test equipment shall be as specified in ISO 834-1. The furnace used shall be related to the
orientation of the test specimen. For horizontal specimens, the floor furnace is applicable.
4.2 Measurement of heat flux from the unexposed surface of specimens shall be made as described in 9.4.
5 Test conditions
Test conditions require the application of the heating and pressure conditions of the standard test for a
loadbearing horizontal separating element as defined in ISO 834-1.
6 Test specimen
6.1 Size of specimen
The test specimen and all its components shall be full size. When this is restricted by the size of the
opening of the furnace (which is normally 3 m × 4 m), the door or shutter assembly shall be tested at
the maximum size possible and the fire resistance of the full-sized assembly shall be derived by an
extended application analysis. However, the minimum dimensions of the supporting construction shall
not be less than that prescribed in 7.3.1.
6.2 Design of specimen
6.2.1 The design of the test specimen and the choice of supporting construction shall take into account
the requirements of 7.3 if the widest field of direct application is to be achieved.
6.2.2 The test specimen shall be fully representative of the door or shutter assembly as intended for
use in practice, including any appropriate surface finishes and fittings which are an essential part of the
specimen and may influence its behaviour in a test construction.

---------------------- Page: 8 ----------------------
ISO 3008-3:2016(E)
6.2.3 If the test specimen is intended for use at an incline other than horizontal, the guidance for
inclined specimens in ISO 3009 shall be followed.
6.3 Verification
6.3.1 The sponsor shall provide a specification to a level of detail sufficient to allow the laboratory
to conduct a detailed examination of the specimen before the test and to agree on the accuracy of the
information supplied. ISO 834-1 provides detailed guidance on verification of the test specimen.
6.3.2 When the method of construction precludes a detailed survey of the specimen without having
to permanently damage it, or if it is considered that it will subsequently be impossible to evaluate
construction details from a post-test examination, then one of two options shall be exercised by the
laboratory, either:
— the laboratory oversees the manufacture of the door or shutter assembly(ies) that is to be the subject
of the test; or
— the sponsor, at the discretion of the laboratory, be requested to supply an additional assembly
or that part of the assembly which cannot be verified (e.g. a door leaf) in addition to the number
required for the testing. The laboratory shall then choose freely which of these shall be subjected to
the testing and which shall be used to verify the construction.
7 Installation of test specimen
7.1 General
7.1.1 The test specimen shall be installed in a manner as intended for use in practice, incorporating all
hardware and other items, which may influence the performance of the specimen.
7.1.2 The test specimen shall be mounted in a supporting construction, the field of application of which
covers the type (see 7.3.1) in which it is intended to be used. The design of the connection between the
test specimen and the supporting construction, including any fixings and materials used to make the
connection shall be as intended for use in practice and shall be regarded as part of the test specimen.
7.1.3 The whole area of the test specimen, together with at least the minimum dimensions of the
supporting construction required by 7.3.1 shall be exposed to the heating conditions.
7.2 Supporting construction
The fire resistance of any supporting construction shall not be determined from a test in conjunction
with a test specimen and shall be at least commensurate with that anticipated for the test specimen.
7.3 Test construction
7.3.1 Associated and supporting construction
The space between the specimen and the frame shall be filled with either
— associated construction, or
— supporting construction.
There shall be a minimum zone of supporting construction of 200 mm wide exposed within the furnace,
each side and over the top of the aperture into which the test specimen is to be fixed. The thickness
of the supporting construction may be increased outside of the 200-mm zone. The test construction
© ISO 2016 – All rights reserved 3
---------------------- Page: 9 ----------------------
ISO 3008-3:2016(E)
may incorporate more than one test specimen providing that there is minimum separation of 200 mm
between each specimen and between the specimens and the edge of the furnace.
7.3.2 Associated construction
When the test specimen is always installed in a specific, normally proprietary, form of construction,
that is permanently associated with its intended use in practice, then the specimen shall be installed in
a sample of this supporting construction.
7.3.3 Supporting construction
7.3.3.1 Where the test specimen is not permanently associated with a specific form of construction,
the area between the test specimen and the support frame shall be filled with a rigid or flexible standard
supporting construction as specified in ISO 834-5.
7.3.3.2 The choice of standard supporting construction shall reflect the range of intended use for
the door or shutter assembly. The rules governing the applicability of the chosen standard supporting
construction to other end use situations are given in Clause 13.
7.4 Gaps
7.4.1 The adjustment of the door leaf, leaves or shutter and gaps shall be within the tolerances of the
design values stipulated by the sponsor. These shall be representative of those used as intended for use
in practice so that appropriate clearances exist, e.g. between the fixed and moveable components.
7.4.2 In order to generate the widest field of direct application, the gaps shall be set between the
middle value and the maximum value within the range of gaps given by the sponsor.
8 Conditioning
8.1 Moisture content
The test specimen shall be conditioned in accordance with ISO 834-1. Requirements for conditioning of
supporting constructions are given in Annex A.
8.2 Mechanical
Some product standards exist for certification purposes that require mechanical testing before the start
of the fire test. Durability requirements are given in the relevant product standard. When mechanical
testing is required, the method used shall follow the requirements of the relevant product standard.
9 Application of instrumentation
9.1 Temperature measurements
9.1.1 Furnace temperature measuring instrument
Plate thermometers shall be provided in accordance with ISO 834-1. They shall be evenly distributed
over a horizontal plane, 100 mm from the nearest plane of the test construction. There shall be at least
2
one plate thermometer for every 1,5 m of the exposed surface area of the test construction, subject to
a minimum of four. The plate thermometer shall be oriented so that “side A” faces the back wall of the
furnace.

---------------------- Page: 10 ----------------------
ISO 3008-3:2016(E)
9.1.2 Unexposed face thermocouples
9.1.2.1 Where no evaluation against the insulation criteria is required of the door or shutter assembly,
or any part thereof, no temperature measurements are required.
9.1.2.2 Where compliance with the insulation criteria is required to be evaluated, thermocouples of
the type specified in ISO 834-1 shall be attached to the unexposed face for the purpose of obtaining the
average and maximum surface temperatures.
9.1.2.3 The temperature of the supporting construction in which the door or shutter assembly is
mounted is not required to be measured and therefore, no thermocouples are required.
9.1.2.4 No thermocouple shall be placed within 50 mm of any hardware.
9.1.2.5 Position five thermocouples (for single or double leaf doors), one at the centre of each specimen
leaf (single or multiple) and one at the centre of each quarter section. These shall not be located closer
than 50 mm to any joint, stiffener or through component, nor closer than 100 mm to the edge of the leaf.
9.1.2.6 For door or shutter assemblies which incorporate discrete areas of different thermal
2
insulation ≥0,1 m (e.g. glazed panels within a door leaf), extra thermocouples shall be evenly distributed
over the sum of the surface of those areas to determine the average temperature at a density of one
thermocouple per square metre or part thereof, subject to a minimum of two. The average insulation
performance of the sum of each area shall be determined.
9.1.2.7 When the total area of a single portion of the door or shutter assembly represents less than
2
0,1 m , it shall be disregarded for the purpose of ascertaining the average unexposed face temperature.
9.1.2.8 Temperature of door leaf or shutter.
Thermocouples shall be fixed to the face of each leaf or shutter as follows:
a) at mid-length, 100 mm in from the edges as specified below;
b) at mid-width, 100 mm from the edge as specified below;
c) 100 mm in from the edges as follows:
1) the inside edges of the clear opening for shutters or sliding doors installed on the exposed side
of the supporting construction;
2) the visible part of the edge of the door leaf for
i) hinged or pivoted doors opening away from the furnace,
ii) shutters or sliding doors installed on the unexposed side of the supporting construction.
If due to the narrow width of the leaf (leaves) or shutter(s) the thermocouples specified in b) and c) are
closer than 500 mm to each other, then those specified in b) are omitted.
If the leaf is <200 mm wide (e.g. as in a multi-leaf folding shutter), then the leaves will be treated
as if they were one leaf with respect to application of unexposed face thermocouples for evaluating
maximum temperature rise.
Additional thermocouples shall be fixed to other areas of the leaf or shutter, e.g. over any through
connection or position where the temperature might be expected to be higher than the mean for the
surface, subject to the limitations given in 9.1.2.9.
© ISO 2016 – All rights reserved 5
---------------------- Page: 11 ----------------------
ISO 3008-3:2016(E)
9.1.2.9 Temperature of other areas.
Thermocouples for determination of the maximum temperature rise of discrete panels of different
thermal insulation within the door leaf shall be applied as for door leaves. However, if there is more
than one other area of the same type then they shall be treated as one large area (as those for the
average temperature rise are). In such cases thermocouples shall avoid any framework adjacent to the
frame leaf.
9.1.2.10 Temperature of door frame.
Thermocouples shall be fixed at each of the following positions:
a) one at mid-length on each long dimension member;
b) one on each of the short dimension members of the frame at mid-width (100 mm away from the
door joint of a multi-leaf door on the primary leaf side);
c) one on each of the short dimension members of the frame 50 mm in from each corner of the leaf
opening.
At each of the positions, thermocouples shall be fixed as close as possible, i.e. with the centre of the disc
15 mm from the junction between the frame and the supporting construction. Irrespective of this, the
distance of these thermocouples from the inside edge of the frame shall not be greater than 100 mm.
For single leaf doors, if due to the narrow width of the opening, the thermocouples specified in b) and c)
are closer than 550 mm to each other, then that specified in b) is omitted.

6 Test specimen
6.1 Size of specimen
The test specimen and all its components shall be full size. When this is restricted by the size of the opening of
the furnace (which is normally 3 m x 4 m), the door or shutter assembly shall be tested at the maximum size
possible and the fire resistance of the full sized assembly shall be derived by an extended application analysis.
However, the minimum dimensions of supporting construction shall not be less than that prescribed in 7.3.1.1.
6.2 Design of specimen
6.2.1 The design of the test specimen and the choice of supporting construction shall take into account the
requirements of 7.3 if the widest field of direct application is to be achieved.
6.2.2 The test specimen shall be fully representative of the door or shutter assembly as intended for use in
practice, including any appropriate surface finishes and fittings which are an essential part of the specimen and
may influence its behaviour in a test construction.
6.2.3 If the test specimen is intended for use at an incline other than horizontal, the guidance for inclined
specimens in ISO 3009 shall be followed.
6.3 Verification
6.3.1 The sponsor shall provide a specification to a level of detail sufficient to allow the laboratory to conduct a
detailed examination of the specimen before the test and to agree on the accuracy of the information supplied.
ISO 834-1 provides detailed guidance on verification of the test specimen.
6.3.2 When the method of construction precludes a detailed survey of the specimen without having to
permanently damage it, or if it is considered that it will subsequently be impossible to evaluate construction details
from a post-test examination, then one of two options shall be exercised by the laboratory, either:
The laboratory shall oversee the manufacture of the door or shutter assembly(ies) that is to be the subject of
the test; or
The sponsor shall, at the discretion of the laboratory, be requested to supply an additional assembly or that
part of the assembly which cannot be verified (e.g. a door leaf) in addition to the number required for the
testing. The laboratory shall then choose freely which of these shall be subjected to the testing and which
shall be used to verify the construction.
7 Installation of test specimen
7.1 General
7.1.1 The test specimen shall be installed in a manner as intended for use in practice, incorporating all
hardware and other items, which may influence the performance of the specimen.
7.1.2 The test specimen shall be mounted in a supporting construction, the field of application of which covers
the type (see 7.3.1.1) in which it is intended to be used. The design of the connection between the test specimen
and the supporting construction, including any fixings and materials used to make the connection shall be as
intended for use in practice and shall be regarded as part of the test specimen.
7.1.3 The whole area of the test specimen, together with at least the minimum dimensions of the supporting
construction required by 7.3.1.1 shall be exposed to the heating conditions.

ISO/WD 3008-3
7.2 Supporting construction
The fire resistance of any supporting construction shall not be determined from a test in conjunction with a test
specimen and shall be at least commensurate with that anticipated for the test specimen.
7.3 Test construction
7.3.1 General
7.3.1.1 Associated and supporting construction
The space between the specimen and the frame shall be filled with either
associated construction or
supporting construction.
There shall be a minimum zone of supporting construction of 200 mm wide exposed within the furnace, each side
and over the top of the aperture into which the test specimen is to be fixed. The thickness of the supporting
construction may be increased outside of the 200 mm zone. The test construction may incorporate more than
one test specimen providing that there is minimum separation of 200 mm between each specimen and between
the specimens and the edge of the furnace.
7.3.1.2 Associated construction
When the test specimen is always installed in a specific, normally proprietary, form of construction, that is
permanently associated with its intended use in practice, then the specimen shall be installed in a sample of this
supporting construction.
7.3.1.3 Supporting construction
7.3.1.3.1 Where the test specimen is not permanently associated with a specific form of construction, the area
between the test specimen and the support frame shall be filled with a rigid or flexible standard supporting
construction as specified in ISO 834-5.
7.3.1.3.2 The choice of standard supporting construction shall reflect the range of intended use for the door or
shutter assembly. The rules governing the applicability of the chosen standard supporting construction to other
end use situations are given in Clause 13.
7.4 Gaps
7.4.1 The adjustment of the door leaf, leaves or shutter and gaps shall be within the tolerances of the design
values stipulated by the sponsor. These shall be representative of those used as intended for use in practice so
that appropriate clearances exist, e.g. between the fixed and moveable components.
7.4.2 In order to generate the widest field of direct application, the gaps shall be set between the middle value
and the maximum value within the range of gaps given by the sponsor.
8 Conditioning
8.1 Moisture content
The test specimen shall be conditioned in accordance with ISO 834-1. Requirements for conditioning of
supporting constructions are given in Annex A.

8.2 Mechanical
Some product standards exist for certification purposes that require mechanical testing before the start of the fire
test. Durability requirements are given in the relevant product standard. When mechanical testing is required, the
method used shall follow the requirements of the relevant product standard.
9 Application of instrumentation
9.1 Temperature measurements
9.1.1 Furnace temperature measuring instrument
Plate thermometers shall be provided in accordance with ISO 834-1. They shall be evenly distributed over a
horizontal plane 100 mm from the nearest plane of the test construction. There shall be at least one plate
2
thermometer for every 1,5 m of the exposed surface area of the test construction, subject to a minimum of four.
The plate thermometer shall be oriented so that ‘side A’ faces the back wall of the furnace.
9.1.2 Unexposed face thermocouples
9.1.2.1 Where no evaluation against the insulation criteria is required of the door or shutter assembly, or any
part thereof, no temperature measurements are required.
9.1.2.2 Where compliance with the insulation criteria is required to be evaluated, thermocouples of the type
specified in ISO 834-1 shall be attached to the unexposed face for the purpose of obtaining the average and
maximum surface temperatures.
9.1.2.3 The temperature of the supporting construction in which the door or shutter assembly is mounted is
not required to be measured and therefore, no thermocouples are required.
9.1.2.4 No thermocouple shall be placed within 50 mm of any hardware.
9.1.2.5 Position five thermocouples (for single or double leaf doors), one at the centre of each specimen
leaf(single or multiple) and one at the centre of each quarter section. These shall not be located closer than 50
mm to any joint, stiffener or through component, nor closer than 100 mm to the edge of the leaf.
2
9.1.2.6 For door or shutter assemblies which incorporate discrete areas of different thermal insulation 0,1 m
(e.g. glazed panels within a door leaf) extra thermocouples shall be evenly distributed over the sum of the surface
of those areas to determine the average temperature at a density of one thermocouple per square metre or part
thereof, subject to a minimum of two. The average insulation performance of the sum of each area shall be
determined.
2
9.1.2.7 When the total area of a single portion of the door or shutter assembly represents less than 0,1 m , it shall
be disregarded for the purpose of ascertaining the average unexposed face temperature.
9.1.2.8 Temperature of door leaf or shutter. Thermocouples shall be fixed to the face of each leaf or shutter as
follows:
1) at mid-length, 100 mm in from the edges as specified below,
2) at mid-width, 100 mm from the edge as specified below,
3) 100 mm in from the edges as follows:
© ISO 2013 – All rights reserved 5
---------------------- Page: 11 ----------------------
ISO/WD 3008-3
i) the inside edges of the clear opening for shutters or sliding doors installed on the exposed side of
the supporting construction, OR,
ii) the visible part of the edge of the door leaf for:
I) hinged or pivoted doors opening away from the furnace,
II) shutters or sliding doors installed on the unexposed side of the supporting construction.
NOTE 1 If due to the narrow width of the leaf (leaves) or shutter(s) the thermocouples specified in 2) and 3) are closer than
500 mm to each other, then those specified in 2) are omitted.
NOTE 2 If the leaf is < 200 mm wide (e.g. as in a multi-leaf folding shutter) then the leaves will be treated as if they were
one leaf with respect to application of unexposed face thermocouples for evaluating maximum temperature rise.
Additional thermocouples shall be fixed to other areas of the leaf or shutter, e.g. over any through connection or
position where the temperature might be expected to be higher than the mean for the surface, subject to the
limitations given in 9.1.2.9.
9.1.2.9 Temperature of other areas. Thermocouples for determination of the maximum temperature rise of
discrete panels of different thermal insulation within the door leaf shall be applied as for door leaves. However, if
there is more than one other area of the same type then they shall be treated as one large area (as those for the
average temperature rise are). In such cases thermocouples shall avoid any framework adjacent to the frame
leaf.
9.1.2.10 Temperature of door frame
Thermocouples shall be fixed at each of the following positions:
1) one at mid-height on each long dimension member,
2) one on each of the short dimension members of the frame at mid-width (100 mm away from the door
joint of a multi-leaf door on the primary leaf side),
3) one on each of the short dimension members of the frame 50 mm in from each corner of the leaf
opening.
At each of the positions, thermocouples shall be fixed as close as possible, i.e., with the centre of the disc 15 mm
from the junction between the frame and the supporting construction. Irrespective of this, the distance of these
thermocouples from the inside edge of the frame shall not be greater than 100 mm.
For single leaf doors, if due to the narrow width of the opening, the thermocouples specified in 2) and 3) are closer
than 550 mm to each other, then that specified in 2) is omitted.
9.2 Maximum temperature
9.2.1 The maximum temperature shall be determined from the five thermocouples fixed to determine the
average temperature rise (as given in 9.1.2.5), the roving thermocouple and from additional thermocouples fixed
as indicated in 9.2.2, 9.1.2.7, 9.1.2.8 and 9.1.2.9.
2
9.2.2 If the door or shutter assembly incorporates discrete areas of different thermal insulation 0,1 m (e.g.
glazed panels within a door or shutter area) which are evaluated separately with respect to average temperature
rise, then the evaluation of maximum unexposed face temperature of those areas shall also be undertaken
separately. This may require extra unexposed surface thermocouples to be applied as given in 9.1.2.6 and
9.1.2.7.
