Test principle:

1. A sample consisting of two vertically angled vertical wings is exposed to the flame produced by the main burner at the bottom of the right angle, the flame is produced by the combustion of propane gas, the propane gas passes through the sandbox burner and produces (30.7 ± 2.0) kW of heat output.

2. The combustion performance of the sample was evaluated by the entire test procedure of 20 min. Performance parameters include: heat release, smoke production, flame propagation and burning dripping and particulate matter.

3. Prior to igniting the main burner, the heat output and smoke generation of the burner itself should be measured for a short time using the auxiliary burner remote from the sample.

4. Some parameters can be measured automatically, while others can be obtained by visual inspection. The smoke pipe is equipped with a sensor for measuring the temperature, light attenuation, the mole fractions of O2 and CO2, and the airflow in the pipeline. These values are automatically recorded and used to calculate the volumetric flow rate, heat release rate (HRR) and smoke rate (SPR).

The transverse propagation and burning of the flame and the particulate matter can be measured using a visual method.
