Introduction
This document is a type C standard as stated in EN 1070.
When provisions of this type C standard are different from those which are stated in type A or B standards, the
provisions of this type C standard take precedence over the provisions of the other standards for lift landing doors
that have been designed and built according to the provisions of this type C standard.
EN 81 has identified the need for certain lift doors to act as fire barriers against the transfer of a fire via the lift well.
This European Standard specifies a procedure for this purpose. It follows the general principle of EN 1363-1, Fire
resistance tests – Part 1: General requirements, and where appropriate the procedure of EN 1634-1, Fire
resistance tests for door and shutter assemblies – Part 1: Fire doors and shutters. Additionally a tracer gas
technique for establishing the integrity of a lift landing door is used.
Lift landing doors are not included in the scope of EN 1634-1.
Lift landing doors, with additional applications, that may already have been tested for other than passenger lift
landing door use to EN 1634-1, are considered to satisfy the corresponding classification according to this
European standard.
1 Scope
This European Standard specifies the method of test for determining the fire resistance of lift landing doors which
may be exposed to a fire from the landing side. The procedure applies to all types of lift landing doors used as a
means of access to lifts in buildings and which are intended to provide a fire barrier to the spread of fire via the lift
well.
The procedure allows for the measurement of integrity and if required the measurement of radiation and thermal
insulation.
No requirements other than the verification that the specimen is operational, are included for mechanical
conditioning before the test as these are included in the relevant product standard.

landing side
4 Test principle
4.1 EN 1634-1 contains a procedure for the determination of fire resistance of doors which may be exposed to a
fire in a building from either side and are required to prevent the transfer of fire from one side to the other. Lift
landing doors represent a special use of doors where the fire exposure is expected to be from a specified direction,
i.e. the landing side, and where the hazard exists only subsequent to the entry of a fire into the lift well. Such a door
is generally not designed to possess the same resistance to the passage of hot gases as a door separating
adjacent spaces on the same floor.
4.2 The test consists of exposing the landing side of a lift landing door to the heating conditions specified in
EN 1363-1 for the period for which the door has to 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.
5 Test equipment
5.1 The test furnace shall be as described in EN 1363-1.
5.2 The canopy shall be as specified in annex A.
5.3 The measuring system for leakage rate shall be as specified in annex A.
6 Test conditions
6.1 The furnace shall be controlled to follow the temperature/time curve as specified in EN 1363-1.
6.2 The furnace shall maintain positive pressure on the exposed side over the whole height of the specimen
such that the pressure at sill level is in the range of (2 ± 2) Pa.
NOTE It is found that the pressure gradient over the height of the specimen is around 8,5 pascals per meter height.
7 Test specimen
7.1 Construction
The test specimen shall be fully representative of the door assembly on which information is required.
7.2 Number of specimens
As information is required when the door is exposed to heating from the landing side only, one specimen is tested.
A second specimen may be required according to 10.2 to verify the door construction.
7.3 Size of specimen
The specimen shall be full size or the maximum size that can be accommodated in the furnace. The typical 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 typical 3 m · 3 m furnace, the opening in the supporting construction is restricted to 2,6 m · 2,8
m (width x height).
7.4 Installation of specimen
The specimen shall be mounted in a supporting construction having adequate fire resistance. 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 to
make the junction, shall be as used in practice with the type of the supporting construction. The position of the door
assembly in relation to the supporting construction shall be as in practice.
The clearances shall correspond to the maximum that is permissible by EN 81-1 and EN 81-2 when the lift landing
doors are put into service, unless designed for another maximum gap size, which shall then apply.
8 Supporting construction
In view of the field of direct application of test results, the lift landing doors shall be erected in the standard
supporting construction as described in annex B.
NOTE In special cases the supporting construction may be of a type with which the door is intended to be used in practice.
In such cases the field of application of the test results is restricted to that construction.
9 Conditioning
9.1 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 and EN 1634-1. No special conditioning procedures
are required where the specimen is constructed primarily from non-hygroscopic materials. Full conditioning of the
supporting construction may not be required if it is known that there will be no effect on the behaviour of the
specimen or the fixing system.
9.2 Samples of materials used in the test door shall be supplied to determine moisture content when necessary.
10 Pre-test examination
10.1 General
Before the test, it shall be verified that the constructional details and clearance gap measurements and depth of
penetration conform to the production and assembly drawings for the door system. It shall also be verified that the
test specimen is operational.
10.2 Constructional details
A full detailed specification of the test specimen shall be provided by the test sponsor prior to its installation at the
laboratory. This specification shall be to a level of detail sufficient to allow the laboratory to conduct a detailed
examination of the specimen before the test and to agree the accuracy of the information supplied. The verification
of the test specimen shall be carried out in accordance with the guidance given in EN 1363-1.
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 post test
examination, then one of two options shall be exercised by the laboratory, either:
a) the laboratory shall request to oversee the manufacturing of the door or shutter assembly(ies) which is to be
the subject of the test; or
b) the sponsor shall be requested to supply an additional assembly or part of the assembly (e.g. a door leaf) to
the number required for test. The laboratory shall then choose freely which of these shall be submitted to the
test and which shall be used to verify the construction.
10.3 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. Sufficient 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 described to an accuracy of
± 0,5 mm. Figure 1 to Figure 4 show different types of lift landing doors and indicate the gaps (g) which need to be
recorded. The depth of penetration and safety guides (if any) shall be measured and recorded.
