Measured Data
Mass Loss Rate (MLR)
Initial-mass-normalized mass loss rate [1/s] was measured in the simultaneous thermal analyzer experiments at three heating rates: 3 K/min, 10 K/min, and 30 K/min and mass loss rate [g/s] in the cone calorimeter at three heat fluxes: 25 kW/m2, 50 kW/m2, and 75 kW/m2.
Cone Calorimeter Test Notes:
In tests HF25_R1 and HF25_R2 a bubble formed between the veneer and the MDF after ignition, which deflated shortly thereafter and released a brief horizontal flame jet from the edge of the sample.
This material forms cracks while burning and warps into an arched shape during the fire decay phase. A representative test picture is available at the link above to Download raw data. Additional replicates or alternative sample preparation (i.e. tie wire method) may be necessary to supplement this data set.
