Table 1 — Fire resistance classes
E 15 20 30 45 60 90 120
EI 15 20 30 45 60 90 120
EW 20 30 60

The fire resistance class of the lift landing door shall be indicated in a data label according to Annex G.

6 Verification
6.1 Test principle

The test consists in exposing the landing side of a lift 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 1 ISO 3008-2 has the same test principle as EN 81-58 based on CO2 measurement.

NOTE 2 EN 1634-1:2014+A1:2018 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.

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 intended floor level.

In some applications such as service lifts or dumbwaiters, the sill level may be different than the intended

floor level.

prEN 81-58:2020 (E)
6.4 Test specimen
6.4.1 Construction

The test specimen shall be fully representative of the door assembly on which information is required.

6.4.2 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 6.7.2 to verify the door construction.

6.4.3 Size of specimen

The specimen shall be full size or the maximum size that can be accommodated in the furnace. The 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 to make the junction, shall be as stated in instructions for use on the type of the supporting

construction. The position of the door assembly in relation to the supporting construction shall be as stated

in instructions for use.

The clearances at the beginning of test shall correspond to the maximum that is permissible by

EN 81-20:2020 when the lift landing doors are put into service, unless designed for another maximum gap

size, which shall then apply.
6.5 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.

6.6 Conditioning

6.6.1 The test specimen, as well as the supporting construction and any sealing materials used, shall be

conditioned in accordance with the requirements of EN 1363-1:2020 and EN 1634-1:2014+A1:2018. 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 there will be

no effect on the behaviour of the specimen or the fixing system.

6.6.2 Samples of materials used in the test door shall be provided to determine moisture content when

necessary.

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 production and assembly drawings for the door system. It shall also be

verified that the test specimen is representative of the product in practice.
6.7.2 Constructional details

A full detailed specification of the test specimen shall be provided. This specification shall be to a level of

detail sufficient to allow 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 1363-1:2020, 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. 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 shows examples of different types of lift landing doors and
