The device is used to measure smoke generation on exposed surfaces of specimens made of materials or composites.

The specimens are exposed to thermal radiation of up to SO kW/m3 generated by an electric cone radiator. The gases de­ taching from the specimen are ignited. The resulting smoke is held in the chamber, and its density is determined using a photometric system.

Alternatively, a gas burner is used in addition to the radia­ tion from the electric radiant heater.

If the device is used for tests according to IMO FTP CODE Annex 1, Part 2, an optional FTIR spectrometer can be con­ nected to determine the proportion of toxic substances in the combustion gas. In addition, the mass-based optical density can be deter­ mined during the test. This is done with the aid of an option­ al weighing module.
