Description
A set of 6 experiments was performed on poly(methyl methacrylate), PMMA. In each test, samples (i.e., 2.44 m tall, 0.61 m wide slabs of PMMA mounted in a parallel panel configuration) were exposed to a propane burner (nominal heat release rate, HRR = 60 kW), which was turned off after sustained flaming was observed across the panel walls. Flames were allowed to spread upward across the panels and continue burning until self-extinction following complete sample burnout.Measurement data obtained in this test series includes:Time-resolved measurements of fire size (kW), soot generation, and gaseous species (CO and CO2) production;Spatially resolved measurements of flame to wall heat transfer [kW/m2];Radiative heat flux at a distance[kW/m2];Initial and final sample mass;Photographs and video of material ignition and fire growth behaviorData will be made publicly available on the MaCFP Repo: https://github.com/MaCFP/macfp-db/tree/master/Fire_Growth/NIST_Parallel_Panel
