Testing the fire behavior of building materials - Determination of the density of smoke emission The device is used to measure smoke generation on exposed surfaces of specimens made of materials or composites. Specimens are exposed to thermal radiation of up to 50 kW/m2 generated by an electric cone heater. The smoke emitted from the specimen is held in the chamber, and its density is determined using a photometric system. Alternatively, a pilot flame burner is additionally used. With the aid of an optional weighing device, the mass-based optical density can be determined. This test is an informative part of DIN EN ISO 5659-2. In addition, with the aid of an FTIR spectroscope (not part of the device), the toxicity of the smoke gases can be determined in accordance with IMO FTP CODE Annex 1, Appendix 2. The result of the smoke obscuration measurement is output as specific optical density. Additional modules
