Measured Data

Carbon Monoxide (CO) Yield

Carbon monoxide yield was measured during cone calorimeter experiments conducted at heat fluxes of 25 kW/m2, 50 kW/m2, and 75 kW/m2.

This material is not combustible. One test per heat flux level was conducted for a duration of 30 minutes. The other replicates were conducted for only 10 minutes based on the observation that no significant mass loss occurred after this time in the first replicates.
