EN 1366 ‘Fire resistance tests for service installations’ consists of the following Parts:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

A typical minimum length to width ratio for a linear joint seal is 10:1. In order to maintain this ratio a

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

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

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

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

The supporting construction shall be of known fire resistance and representative of that used in

practice. The supporting construction for test purposes shall be as shown in Figures 26, 27 and 28. The

supporting construction may be either one of the standard constructions listed in 7.2.2 or a specific
