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.
In each cone calorimeter test the polyester fabric shrivelled upon heating and impacted the spark ignitor, causing spikes in the mass time history data. The sample then retracted away from the spark ignitor prior to ignition due to further pyrolysis and melting of the materials. Additional replicates with alternative sample preparation may be necessary to supplement this data set. Representative test pictures are available at the link above to Download raw data.
