Fire Testing


For Determining the Performance of Roofs when Exposed to External Fire

Test 3, incorporating incendiary devices, wind and supplementary radiant heat in accordance with DIN CEN/TS 1187

The DIN CEN/TS 1187 standard specifies four test methods for determining the fire behavior of roofs when exposed to external fire. The TDP T3 allows for a test in accordance with test method 3.

Test method 3 assesses:

  • The fire spread on the roof surfaceThe fire spread within the roof structure
  • The penetration of the roof by fire, and
  • The occurrence/dropping/falling of burning or molten material

Testing of Multi-Layer Roof Structures under Realistic Environmental Conditions

From a fire protection perspective, roofs should be considered to be a system. In certain countries, along with classification of the fire behavior of the individual components used, the fire behavior of the entire roof structure must therefore also be assessed.*

The TDP T3 measures specimens that are representative of the roof assembly in terms of the type and number of roof layers, including existing thermal insulation layers, vapor barriers, etc.

Specimens with a minimum width of 1.2 m and minimum length of 3 m are tested.

In order to carry out a test in accordance with test method 3, the use of a wind device and a radiant heater is required in addition to incendiary devices consisting of a roof construction. The TDP T3 is equipped with a wind device allowing for a defined air flow to be set parallel to the specimen. The heat radiator mounted above ensures symmetrical heat flow distribution on the surface of the specimen. This provides realistic conditions for investigating the fire behavior of a roof structure.

The tiltable sample holder allows for the testing of specific roof pitches. The movable base of the wind device enables positioning at the correct distance from the specimen. The radiant heater of the TDP T3 is attached to the frame of the test rack and can be adjusted in height to set the required distance from the specimen.
