FIRE RESISTANCE OF CLT JOINTS

The project aims to measure the fire resistance performance of certain types of CLT joints through a series of tests.

The tests were carried out according to UNI EN 1363-1:2020 "Fire resistance tests - Part 1: General requirements" in which the general principles for determining the fire resistance of various building elements subjected to standardised fire exposure conditions are defined. The specimen is exposed to fire from below (intrados).

TYPES OF JOINT

PERFORMANCE CRITERIA

The criteria for assessing the performance of the test specimen are detailed in EN 1363-1: 2020. The performance of the test specimen is measured by the time, expressed in full minutes (i.e. net of seconds), in which the specimen continues to meet the performance criteria described below.

TIGHTNESS

The time in full minutes during which the specimen continues to maintain its separation function without:

• causing a cotton swab to ignite

• allowing the penetration of a feeler gauge

• developing persistent flames

INSULATION

The time in full minutes during which the specimen continues to maintain its separation function, without developing temperatures on the surface not exposed to fire that exceed the initial average temperature at all sensor positions (including the moving thermocouple) by 180 K.

Note: increments refer to the average initial temperature measured on the side not exposed to fire of the test specimen.
