Mass Loss Rate (MLR)

Mass loss rate [kg/s] was measured in cone calorimeter experiments at three heat fluxes: 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.

Heat Release Rate Per Unit Area (HRRPUA)

Experiments for heat release per unit area [kW/m2] were conducted on samples conditioned at 20°C and 50% relative humidity using a cone calorimeter at three different heat fluxes: 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.
