EN 1366-4:2021 (E)
Introduction

Linear joint seals are positioned in joints, voids, gaps or other discontinuities within one or between

two or more construction elements.

Normally such openings are denoted as linear because their length is greater than their width - defined

by a typical ratio of at least 10:1 in practice.
Joints are present in buildings due to the following:

a) acceptable dimensional tolerances between two or more building elements, e.g. between non-load

bearing walls and floors;

b) by design to accommodate various movements induced by thermal differentials, seismicity and

movement induced by wind loads;

c) as a result of inadequate design, inaccurate assembly, repairs or damage to the building.

The purpose of the tests in this document is to assess:

d) the effect of a linear joint seal on the integrity and insulation of the construction;

e) the integrity and insulation performance of the linear joint seal;

f) the effect of movement within the supporting construction on the fire resistance performance of

linear joint seals (see Annex B).

The results of these tests are one factor in assessing the fire resistance performance of joint seals.

Annex A describes the principles of standard conditions for linear joint seals where no mechanically

induced relative movement occurs between the joint faces.

Annex B provides standard conditions for joints with mechanically induced movement of opposing joint

faces.

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 the test elements or structures, during their testing and

during the disposal of test residues.

An assessment of all potential hazards and risks to health should be made and safety precautions

should be identified and provided. Written safety instructions should be issued. Appropriate training

should be given to relevant personnel. Laboratory personnel should ensure that they follow written

safety instructions at all times.

1 Scope

This part of the EN 1366 series specifies a method for determining the fire resistance of linear joint

seals based on their intended end use. Perimeter seals of curtain walling are excluded from this part of

the EN 1366 series.
This document is intended to be used in conjunction with EN 1363-1.
The following tests are included in this document:
— no mechanically induced movement;
— mechanically induced movement.

Tests in accordance with this part of the EN 1366 series are not intended 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 noted in the test report in describing the general behaviour of test

specimens during the test.

The load-bearing capacity of a linear joint seal is not addressed in this part of the EN 1366 series. No

information can be implied by the test concerning the influence of the inclusion of linear joint seals on

the loadbearing capacity of the separating element.

3.1
linear joint

linear void having a length to width ratio of at least 10:1 within one or between two or more juxtaposed

construction elements

Note 1 to entry: Typical locations of linear joints include floors, the perimeter of floors, walls, ceilings and roofs.

3.2
linear joint seal

system designed to maintain the fire separating function and, if relevant, to accommodate a specified

degree of movement within the linear joint
3.3
movement capability

maximum amount of movement the joint seal is able to tolerate as stated by the manufacturer or the

test sponsor, expressed as a percentage of the nominal width

Note 1 to entry: The percentage given is not the total displacement between minimum and maximum joint

width, but the displacement in one direction, e.g. for lateral movement either elongation (+x%) or compression

(-x%).

Note 2 to entry: The movement capability is usually the same over the entire range of the nominal widths.

3.4
nominal joint width

specified width of a joint seal, to be selected by the manufacturer or test sponsor

3.5
splice
connection or junction between or within the length of a linear joint seal
3.6
supporting construction

construction that may be required for the testing of some separating elements into which the test

specimen is assembled, e.g. the wall into which a linear joint seal is fitted
3.7
test construction

complete assembly of the test specimen(s) together with its supporting construction

3.8
test specimen

linear joint seal of a specific material, design and dimensions provided for the purpose of determining

either its fire resistance or its contribution to the fire resistance of another separating element

4 Test equipment

In addition to the test equipment specified in EN 1363-1, and if applicable EN 1363-2, the internal

dimensions of the test furnace shall be such that a distance of at least 200 mm exists between the long

edge of a linear joint and the wall of the furnace, subject to a minimum internal size of

1 m × 1 m × 0,75 m. Where the nominal width of the linear joint seal is greater than 300 mm, the

internal size of the furnace shall be at least 3 m × 3 m × 0,75 m (see 6.2). Where the nominal width of

the linear joint seal in the test specimen is greater than 100 mm and less than or equal to 300 mm, the

---------------------- Page: 10 ----------------------
SIST EN 1366-4:2021
EN 1366-4:2021 (E)

size of the furnace shall at least be able to heat a length of 10 times the nominal width of the linear joint,

subject to deviations from this rule given in 6.2.
5 Test conditions
5.1 Heating conditions

The heating and furnace atmosphere shall conform to those given in EN 1363-1 or, if applicable,

EN 1363-2.
5.2 Pressure conditions

A vertical furnace shall be operated so that a minimum pressure of 15 Pa exists in the centre of the test

specimen mounted in the lowest position.

A horizontal furnace shall be operated so that a pressure of (20 ± 3) Pa is established at a position

(100 ± 10) mm below the lowest point of the test construction.
6 Test specimen
6.1 General

The test specimen consists of a linear joint seal. One test specimen shall be prepared for each type of

supporting construction and type of movement, if relevant, for which the sponsor seeks classification

(see Annexes A and B).
6.2 Size

A linear joint seal shall be of uniform design cross-sectional area and of the maximum length that can be

accommodated in the separating element selected for test. For non-movement joints a shorter length

may be used subject to a minimum of 900 mm. In order to avoid boundary effects, the distance between

the long edge of the linear joint seal and the outer perimeter of the heated part of the separating

element shall be not less than 200 mm at any point.

A typical minimum length to width ratio for a linear joint seal is 10:1. The length to width ratio may be <

10:1 in case the heated length of the linear joint seal is ≥ 2 600 mm.
6.3 Number of test specimens

In the case of vertical elements two tests shall be carried out, one from each direction of exposure. If in

practice the fire risk can be identified as coming from one side only, or where the linear joint seal is fully

symmetrical, then only one specimen may be tested with the appropriate face exposed to the heating

regime.

Where it can be established clearly in a non-symmetrical construction that there is a weaker direction

of exposure only one specimen may be tested. In such a case, a full justification for the procedure

adopted shall be included in the report.

In the case of horizontal elements the test specimen shall be exposed to heating from the underside.

Where a linear joint seal is intended for use in both horizontal and vertical separating elements, each

orientation shall be tested.

7 Installation of test specimen
7.1 General

All materials used in the construction, fabrication and installation process of the test specimen shall be

representative of the design, materials and workmanship of those to be used in practice.

Where voids exist within a linear joint seal (e.g. when it is in the form of a tube), the ends shall be

hermetically sealed in order to prevent airflow through the test specimen. For tests with movement, the

sealing of the voids shall be done after imposing the movement to avoid damaging the seal during the

movement.

When a primer is part of the system, it shall be included in the test. Each primer shall be tested

separately.
The standard conditions are given in Annexes A and B.
7.2 Requirements for specific seal types
7.2.1 Seals made of fabrics
For definitions of the relevant dimensions see Figure 1.

For seals made of either various thicknesses or several layers of one thickness of fabric the maximum

nominal joint width shall be used with the relating intended number of layers in the seal and with the

minimum and maximum (if relevant) material thickness for the intended fire resistance performance.
