Hydrogenated tetrapropylene fire tests

25/11/2010

 

 

The IRSN is conducting fire testing to characterize the combustion of homogeneous plastics (PVC, polyethylene, etc.) and heterogeneous plastics (mixtures of these), and to qualify the soot metrology experimental techniques.

 

Mise au point de dispositif expérimental. Essais de feux de TPH réalisé dans un bac  métallique de 5 cm de profondeur. 

In order to adjust the experimental protocol, HTP (hydrogenated tetrapropylene, C12H26) fires are set in a 5-cm deep metal tank. During combustion, as the tank temperature rises, bubbles appear on the surface of the liquid, and then drops are projected toward the exterior. These burning drops create the very characteristic filaments seen around the tank.
