Critical Mass Flowrate At The Firepoint Of Plastics

Thomson, H.E. and Drysdale, D.D., 1989. Critical Mass Flowrate At The Firepoint Of Plastics. Fire Safety Science 2: 67-76. doi:10.3801/IAFSS.FSS.2-67


The critical mass flux at the fire point for eight common thermoplastics (including two fire retarded modifications) has been measured by exposing horizontal samples to irradiance levels in the range 12-35kw/m² and monitoring their weight loss. The results are significantly lower than values reported elsewhere: this may be attributed to differences in the convective heat transfer coefficient at the surface.
