Landing doors act as fire barriers against the transfer of a fire via the lift well. This document specifies
requirements for this purpose. It follows the general principle of EN 1363-1:2020 and where appropriate
the procedure of EN 1634-1:2014+A1:2018. Additionally, a tracer gas technique for establishing the
integrity of a landing door is used.

1 Scope
This document defines the fire resistance test and requirements for landing doors which are intended to
provide a barrier to the spread of fire from the landing side and via the lift well in buildings for a period
of time classified in this document. The fire resistance requirements are expressed in terms of integrity
(E), insulation (EI) and radiation (EW).
It is applicable to landing doors installed in the lift well openings at landings and used as means of access
to lift car.
It also specifies the method of testing and classification of fire resistance of landing doors. The test
method is only valid for furnaces where the door is mounted in a vertical position. The test method
specifies the measurement of integrity and if required the measurement of radiation and thermal
insulation.
This document refers to CO as means of tracing the propagation of fire. The document does not cover
hazards due to emission of gases.
This document is not applicable to landing doors which are installed before the date of its publication.

6 Verification of safety requirements and/or protective measures
6.1 Test principle
The test consists in exposing the landing side of a landing door to the heating conditions specified in
EN 1363-1:2020 for the period for which the door shall be assessed for its fire resistance. During the test,
positive pressure exists over the whole height of the door on the exposed side, inducing the leakage of
furnace gases to the unheated side. A canopy is provided on the unexposed side which collects the leaked
gases and a suction fan draws these through a duct provided with a system for measuring the volume
flow (see Annex A). The concentration of CO , used as a tracer gas, is measured in the furnace and at the
airflow measuring point, and by monitoring the gas flow rate and its temperature it is possible to calculate
the leakage rate of hot gases through the test door. The method gives a record of the hot gas leakage as a
function of time which is corrected for normal conditions. This provides a basis for assessing the ability
of the door to act as an effective fire barrier.
NOTE ISO 3008-2:2017 has the same test principle as EN 81-58 based on CO measurement.
6.2 Test equipment
6.2.1 The test furnace shall be as described in EN 1363-1:2020.
6.2.2 The canopy shall be as specified in Annex A.
6.2.3 The measuring system for leakage rate shall be as specified in Annex A.
6.3 Test conditions
6.3.1 The furnace shall be controlled to follow the temperature/time curve as specified in
EN 1363-1:2020.
6.3.2 The furnace shall maintain positive pressure on the exposed side over the whole height of the
specimen such that the pressure at the sill level is in the range of (2 + 8,5 × H ) ± 2 Pa where H is the
sill sill
vertical distance (in metres) between the sill level and the landing floor level.
NOTE In some applications such as service lifts or dumbwaiters, the sill level is higher than the landing floor
level.
6.4 Test specimen
6.4.1 Construction
The test specimen shall be according to the technical specification of the door assembly.
6.4.2 Number of test specimens
As information is required when the door is exposed to heating from the landing side only, one specimen
shall be tested.
6.4.3 Size of specimen
The specimen shall be full size or the maximum size that can be accommodated in the furnace. The
reference size of the front opening of the furnace is 3 m × 3 m. In order to expose a required minimum
width of 200 mm of supporting construction for a 3 m × 3 m furnace, the opening in the supporting
construction is restricted to 2,6 m × 2,8 m (width × height).
6.4.4 Installation of specimen
The specimen shall be mounted in a supporting construction having at least the fire resistance of the
target classification. The supporting construction shall be built first within the test frame leaving an
aperture of the specified size. The width of the supporting construction on the two vertical sides and the
top shall be not less than 200 mm.
The design of the connection between the door and the supporting construction, including any materials
used for the fixation and the sealing, shall be as stated in the information for use on the type of the
supporting construction used for the test. The position of the door assembly in relation to the supporting
construction shall be according to the information for use of the door.
6.4.5 Adjustment of specimen
The specimen shall be adjusted so that the clearances between door panels, or between panels and
uprights, lintels or sills at the beginning of test shall correspond to those specified in the information for
use.
6.5 Supporting construction
For the field of direct application test results (see 6.12), the landing doors shall be erected in the standard
supporting construction as described in Annex B.
6.6 Conditioning
The test specimen, as well as the supporting construction and any sealing materials used, shall be
conditioned in accordance with the requirements of EN 1363-1:2020, 8.2, and EN 1634-1:2014+A1:2018,
8.1 and Annex A. No special conditioning procedures are required where the specimen is constructed
primarily from non-hygroscopic materials.
6.7 Pre-test examination
6.7.1 General
Before the test, it shall be verified that the constructional details and clearance gap measurements and
depth of penetration conform to the specifications.
6.7.2 Constructional details
A full detailed specification of the test specimen shall be provided. The verification of the test specimen
shall be carried out in accordance with the guidance given in EN 1363-1:2020, 6.5.
6.7.3 Clearance gap measurements and depth of penetration
The clearances between the moving components and the fixed parts of the door assembly shall be
measured prior to the test. Measurements shall be made to adequately describe the nature of the gaps
and there shall be a minimum of three measurements along each side or edge. The gap sizes shall be

measuring device and the absolute pressure in relation to the ambient conditions. The range of the
instrument shall be compatible with the flow rate generated by the suction fan.
NOTE Between the sampling probes and the cooling equipment the gases are transferred through a heated line
to prevent condensation. It is advised to use a time shift when the data are measured to accommodate the response
time between the CO data and temperature and pressure data (see Annex E, E.1).
The accuracy of determination of leakage rate shall be within 10 %.
6.8.4 Furnace pressure
Furnace pressure shall be measured continuously at a minimum of two locations over the height of the
furnace to ensure that the pressure conforms to the specification in 6.3.2.
6.8.5 Unexposed face temperature
6.8.5.1 General
This clause specifies additional details for testing insulating capacity of landing doors.
Where compliance with the insulation criteria is required to be evaluated, thermocouples of the type
specified in EN 1363-1:2020 shall be attached to the unexposed face as indicated below for the purpose
of obtaining the average and maximum surface temperatures. General principles for the attachment of
thermocouples given in EN 1363-1:2020 shall apply.
The dimensions given in 6.8.5.2 and 6.8.5.3 shall be taken from landing side.
Where no evaluation against the insulation criteria is required of the door, or any part thereof, no
temperature measurements are required.
6.8.5.2 Position of the thermocouples to determine the average temperature
6.8.5.2.1 Door panel(s)
For door panel(s) width greater than 400 mm, five thermocouples shall be positioned per door panel, one
to the centre of the door panel and one to the centre of each quarter section.
For door panel(s) width greater than 300 mm but less than 400 mm, the thermocouples at the centre of
quarter sections shall be repositioned horizontally so that they are 100 mm away from the vertical edges
of the panel.
For door panel(s) width less than 300 mm, three thermocouples shall be positioned per door panel, one
to the centre of the door panel and one to the centre of upper and lower half section.
The position of the thermocouples may be adjusted from the positions defined above to a maximum
distance of 50 mm to avoid the measurement directly from top of a joint, stiffener or a through
component. In adjusting the position, the minimum distance of 100 mm from the edges of the panel shall
be maintained.
When the total area of a single part of the door assembly is equal or smaller than 0,2 m , it shall be
disregarded for the purpose of ascertaining the mean unexposed face temperature.
6.8.5.2.2 Door frame
The door frame of landing doors can include the following parts; the horizontal top member which may
include the door mechanism (on sliding and folding doors), two vertical members and an over panel. No
thermocouples shall be placed on the horizontal top member including the door mechanism.
The side panels and over panels more than 300 mm width or height shall be provided with one
thermocouple for each square meter or part thereof, subject to a minimum of two thermocouples.
These thermocouples shall not be located closer than 100 mm to any joint, stiffener or through
component, nor closer than 100 mm to the edge of the side/over panel.
If the height of the over panels or width of the side panels are equal or smaller than 300 mm no
thermocouples are required for determining the mean temperature rise.
The average insulation performance of each area shall be determined.
6.8.5.3 Position of the thermocouples to determine the maximum temperature
6.8.5.3.1 Door panel(s)
The maximum temperature shall be determined from the thermocouples fixed to determine the mean
temperature rise (as given in 6.8.5.2.1).
6.8.5.3.2 Door frame
The maximum temperature shall be determined from the thermocouples fixed to determine the mean
temperature rise (as given in 6.8.5.2.2). For side panel width and over panel height greater than 300 mm,
these shall be provided with one thermocouple for each square meter or part thereof, subject to a
minimum of two thermocouples. For side panel width and over panel height between 300 mm and
100 mm only one thermocouple shall be fixed at the centre of each member. For side panel width and
over panel height less than or equal 100 mm no temperature measurements are required.
6.8.6 Radiation measurement
If there is a requirement for the specimen door to satisfy the radiation criteria, appropriate
instrumentation, as described in EN 1363-2:1999 shall be provided to measure radiation from the
unexposed face. In order to allow the location of the radiometer at 1 m from the exposed face, as specified
in EN 1363-2:1999, an adapted aperture may need to be cut in the curtain.
6.8.7 Deformation measurement
If requested, the deformation shall be measured and recorded at specified locations, see locations “d” in
Figure 1 to Figure 4.
In the case of a swing door the deformation measurement is performed at (100 ± 5) mm from the top and
the bottom of the door and in the middle of the door height (see Figure 1).
In the case of door configurations according to Figures 2 and 3 the deformation measurements are
performed at
— in the vertical direction (100 ± 5) mm from the bottom of the door panels, and in the middle of the
door panels height, and
— in the horizontal direction at the maximum 15 mm distance from the vertical edges of the door
panels.
In the case of multi-panel sliding door according to Figure 4 the deformation measurements are
performed at
— in the vertical direction (100 ± 5) mm from the top and the bottom, and in the middle of the clear
height (H) of the door, and
— in the horizontal direction at the maximum 15 mm distance from the vertical edges of the door panels
and in the middle of the clear width (W) of the door.
Precautions shall be taken that the insulation material is not affected during the test.
The minimum distance between deformation measurement point and thermocouple measurement point
shall be 50 mm. In case the distance is less than 50 mm, the deformation measurement points shall be
moved so, that the distance is (55 ± 5) mm.
If deformation is measured by a cable through the canopy, diameter of holes in the canopy shall be no
more than 1 mm larger than diameter of the cable.
Deformation measurements (d) shall be recorded if the panel or side frame width is greater than or equal
to 300 mm.
NOTE In Figures 1 to 4, the width of the frame is less than 300 mm.
6.8.8 Flow measurement verification
The reliability and the adequacy of the leakage rate measurement system shall be established prior to the
start of the furnace test according to Annex D using the CO calibration burner shown in Figure D.1 and
Figure D.2.
Provisions shall be made during the verification test to protect the landing door against radiation or
heating by the CO calibration burner.
Action shall be taken to reduce any difference between the theoretical and measured flow rate and CO
concentration of more than 10 %. If the difference is lower than 10 % the leakage rate of the test shall be
corrected for this difference using Formula (D.1).
6.9 Test method
The test specimen shall be located in front of the furnace to provide a sealed furnace chamber. The
accuracy of the CO measuring system checked and the flow measurement verification of 6.8.8
undertaken.
On satisfactory completion of this check the exhaust fan shall remain in operation and the furnace ignited.
It shall be controlled to follow the standard heating curve of EN 1363-1:2020.
At the commencement of the test, the plate thermometers shall be 100 mm from the nearest plane of the
exposed face of the test construction.
The data from the flow measuring instrumentation and the CO concentration in the furnace shall be
recorded for analysis during the test, including the flow measurement verification (6.8.8). If the
unexposed face temperatures, radiation from this face and door deformation is being measured, these
data shall also be recorded. The time of the occurrence of flaming, and its duration shall be recorded.
Observations shall be made of the general behaviour of the door specimen during the course of the test
and notes made concerning deformation, opening of the gaps, melting or softening of materials, charring
of surface finishes, etc. If quantities of smoke are emitted from the unexposed face this shall be noted.
6.10 Test termination
The test shall be terminated according to EN 1363-1:2020, 10.5.
6.11 Assessment of performance
6.11.1 The performance of the specimen door shall be expressed in terms of integrity (E), insulation (I)
and radiation (W) given in Clause 4.
6.11.2 The leakage rate through the door shall be corrected to normal temperature and pressure
conditions and expressed as m /min, in accordance with Annex E. The limit values for acceptable leakage
rates are given in 4.2.
NOTE Transient peaks in the observed leakage rate curve can be ignored if they are due to fluctuations in the
measuring chain and do not correspond to any real increase in leakage rate as a result of increasing gaps or further
dislocations in the specimen.
The presence of combustible materials (coatings, paint) which pyrolyze at a given temperature after a
certain time may give rise to a temporary increase in the observed CO -production which does not
correspond to an increase of the leakage rate and shall therefore be disregarded for the data used for
classification.
6.11.3 The insulation of the door, where required to be established, shall be judged on the basis of either
temperature rise of the unexposed face or radiation emitted from this face. The appropriate criteria are
given in 4.3 and 4.4.
6.12 Field of direct application
Test results fulfilling with the criteria given in 6.11 in terms of Integrity (E), and Thermal Insulation (I)
shall be considered applicable to doors of sizes different from those of the test specimens, all other
constructional details being the same, within the following limitations:
1) a door with lower height than the tested specimen;
2) a door with a door opening or an opening width in the wall equal to the one tested within a range
of ±30 %;
3) a door with greater height of up to 15 %: in that case the corrected leakage rate shall be extrapolated
according to Annex F.
The limitations given above may be applied together.
If tested in a standard supporting construction, the results are valid for all constructions with a density
equal to or greater than 600 kg/m and thickness equal to or greater than 100 mm.
The results of doors tested with a supporting construction different from the standard supporting
constructions as described in Annex B are restricted to that specific supporting construction.
6.13 Test report
The test report shall provide the general information required according to the relevant provisions of
EN 1363-1:2020, 12.1 and EN 1634-1:2014+A1:2018, Clause 12 (excluding items a) and g)). In addition,
the following data shall be provided:
a) the leakage rate through the door during the course of the test;
b) the time and duration of the occurrence of flaming;
c) the deformation of the door, as a function of time, if requested (see 6.8.7);
d) radiation emission when measured, as a function of time;
