European foreword
This document (prEN 1366-14:2023) has been prepared by Technical Committee CEN/TC 127 “Fire
safety in buildings”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
This document has been prepared under a standardization request addressed to CEN by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.
EN 1366 ‘Fire resistance tests for device installations’ consists of the following Parts:
— Part 1: Ducts
— Part 2: Fire dampers
— Part 3: Penetration seals
— Part 4: Linear joint seals
— Part 5: Device ducts and shafts
— Part 6: Raised access and hollow core floors
— Part 7: Conveyor systems and their closures
— Part 8: Smoke extraction ducts
— Part 9: Single compartment smoke extraction ducts
— Part 10: Smoke control dampers
— Part 11: Fire protective systems for cable systems and associated components
— Part 12: Non-mechanical fire barrier for ventilation ductwork
— Part 13: Chimneys
— Part 14: Partial penetration seals (this document)

1 Scope
This part of the EN 1366 series specifies a method of test and criteria for the evaluation (including field
of direct application rules) of the ability of a partial penetration seal to maintain the fire resistance of a
separating element at the position at which it has been penetrated by a device or devices that passes
through one face of the element only. Partial penetration seals are used to seal apertures for electrical
sockets, downlighters, media devices, cables and any item which requires an opening to be made in one
face of the element of construction but does not include a device which passes through both faces.
Supporting constructions are used in this part of the EN 1366 series to represent separating elements
such as walls or floors. These simulate the interaction between the test specimen and the separating
element into which the sealing system is to be installed in practice.
This part of the EN 1366 series is used in conjunction with EN 1363-1.
The purpose of a test described in this part of the EN 1366 series is to assess the integrity and insulation
performance of the partial penetration seal, of the penetrating service(s) or device(s) and of the
separating element in the surrounding area of the partial penetration seal. Where partial penetration
seals are installed in ceilings and floors, the loadbearing capacity shall also be considered.
No information can be implied by the test concerning the influence of the inclusion of such penetrations
and penetration seals on the loadbearing capacity of walls.
It is not the intention of this test to provide quantitative information on the rate of leakage of smoke
and/or hot gases or on the transmission or generation of fumes. Such phenomena are only to be noted in
the test report in describing the general behaviour of test specimens during the test.
Tests in accordance with this part of the EN 1366 series are not intended to supply any information on
the ability of the partial penetration seal to withstand stress caused by movements or displacements of
the penetrating devices.
The risk of spread of fire downwards cannot be assessed with this test.
Tests in accordance with this part of the EN 1366 series do not address any risks associated with leakage
of dangerous liquids or gases caused by failure of the device in case of fire.

Partial penetration seals for walls shall be tested in a wall with minimum dimensions of 3 m high × 1,2 m
wide.
Partial penetration seals for ceilings shall be tested in a floor/ceiling construction, with minimum
dimensions of 4 m × 3 m (with a minimum span of 4 m).
In order to avoid boundary effects, the distance between the perimeter of the partial penetration seal and
the internal surfaces of the furnace shall be not less than 200 mm at any point.
Separation of partial penetration seals installed within the same face of a wall construction shall comply
with the following:
a) partial penetration seals that are intended to be evaluated separately shall be separated by a
minimum 200 mm vertically or horizontally in the plane of the wall, unless the separation distance
used in practice is less, in which case the actual separation distance shall be used;
b) partial penetration seals that are intended to be evaluated with interaction, shall be tested with a
separation of less than 200 mm (vertically or horizontally in the plane of the wall), unless the
separation distance used in practice is less. In each case the actual separation distance used shall be
the desired minimum separation;

less than 200 mm (horizontally or vertically in the plane of the wall).
Separation of partial penetration seals installed within the opposite faces of a wall construction shall
comply with the following:
a) the centre point of partial penetration seals that are intended to be evaluated separately shall be
separated by a minimum 200 mm vertically or horizontally in the plane of the wall, unless the

c) the distances (both vertical and horizontal in the plane of the wall) between the centre points of
partial penetration seals shall be recorded in the test report wherever this is less than 200 mm

Annex F provides an alternative test method for partial penetrations seals in wall or floor constructions
that have already been subject to a fire test.
6.2 Number of test specimens

7 Installation of test specimen
7.1 General
The test specimen(s) shall be installed, as far as possible, in a manner representative of their use in
practice, including any associated required wiring etc. Care shall be taken to avoid any artificial support
which could be provided to the device, e.g. if it sags during the test.
When more than one test specimen is incorporated into a single supporting construction, care shall be
taken to ensure that there is no interaction between different test specimens, except if the determination
of the interaction is the intention of the test.
7.2 Supporting construction
7.2.1 Standard flexible wall constructions
The standard supporting construction shall be in accordance with the provisions given in EN 1363-1,
except where modified by provisions within this document.
The size of the flexible wall shall be as defined in 6.1. The wall shall be restrained only on the top and
bottom edge. A construction omitting insulation shall be used.
The overall thickness and number of the gypsum board(s) shall be as given in Table 1. Steel studs of
varying widths may be used to fit the flexible wall constructions defined in Table 1. At the discretion of
the test sponsor, a lower specification for any of the parameters in Table 1 may be selected for the test
and the direct field of application rules applied relative to the tested parameters.

7.2.2 Flexible floor/ plasterboard ceiling constructions
7.2.2.1 General
Currently there is no defined standard supporting construction for flexible floors/plasterboard ceiling
constructions, however Annex G (informative) provides guidance for timber joist constructions that may
be used for test periods of up to 90 min. The size of the flexible floor shall be as defined in 6.1. The floor
