• Reflection panel is composed of a cast iron frame with vertically applied porosity fire resistant material with a 305X457mm size exposed reflection surface and is designed to function at 815 ¡É.
• The Calibration burner should have 1.8mm holes in 16mm intervals, and should be manufactured along the middle line.
• An exhaustion device with a 0.5 m/s airflow exhaustion rate is installed.
• In order to control the surface heat of the reflection panel, a 180¡É ~ 230¡É (Black body temperature) range will be given, and a ¡¾5¡É accuracy, fit to observe a surface of 250mm radius at 2 m distance.
• Exposure time and whether the specimen was completely
  destroyed or was expose for 15min.
• Average radiant panel index (Is) for each set of specimens,
  rounded to the nearest multiple of five.
• The simple ratio of a temperature rise of 100¡É to the heat
  input in kilowatts producing it. (Beta)
• Flame spread factor (Fs)
• Heat evolution factor (Q)
• Visual burning characteristics of Specimens
