Radiant Heat Panel Discussion Subgroup Topics l Flame Propagation l Nozzle Angle l Heat Flux Check l Post-Calibration l Additional Round Robins

Radiant Heat Panel Discussion l Foams – Expand – Exhibit Intumescence – As a result of this expansion and/or intumesence, these samples tend to: Extinguish the Pilot Burner Flame l Redirect the Pilot Burner Flame l Expand in to the Pilot Burner Flame l l This may also occur with “Cloth” type Materials
