ACM PE, PIR, rep 2
Aluminium Composite Material (ACM) PE
Description
This experiment is on a system consisting of an Aluminium Composite Material (ACM) PE cladding panel and a Polyisocyanurate (PIR) foam insulation panel, separated with a cavity of 50 mm width. It is the second repetition of this system configuration.
Experiment Notes
At approximately 1 minute the PE core began to drip from the ACM panel, and continued to burn within the debris tray. At 3 minutes, the fire size reduces as mechanical effects limit the pyrolysis of the polyethylene core. This is overcome at 5 minutes as the fire begins to grow again where flaming grows at the edges of the panels and the polyethylene core begins to pyrolyse and drip into the debris tray again. At approximately 6 minutes, smoking droplets were observed coming out from the sides of the ACM PE panel.
