Main parameters

Figra 0.2MJ - Combustion Growth Rate Index. The maximum value of the ratio of the heat release rate of the sample to the exposure time after the critical value of THR reaches 0.2 MJ.

2. Figra 0.4MJ - Combustion Growth Rate Index. The maximum value of the ratio of the heat release rate of the sample to the exposure time after the THR critical value reaches 0.4 MJ.

3. THR600S - The total heat release of the sample within the first 600 seconds after being exposed to the main burner.

4. SMOGRA - Flue Gas Generation Rate Index. The maximum value of the ratio of the smoke production rate of the sample to the required exposure time.

5. TSP600S - The total smoke production of the sample within the first 600 seconds after being exposed to the main burner.

6. LFS - Lateral propagation of flame on the long wing of the specimen.

Test phenomena: Record collapse, deformation, molten droplets, spread and burning droplets, etc. The observation results of burning droplets are the determination parameters for the additional classification d.
