Test Procedures

Install the sample in the combustion chamber using the appropriate sample holder.

Connect the G112 test gas supply.

Start the quartz heaters and T-shaped burner, providing thermal radiation and flame exposure.

Adjust heater power automatically according to the test schedule:

First 2 min 45 s: initial burner exposure at 530 J/s

At 2:45 min: increase total heater power to 1800 W

At 5 min: reduce power to 1500 W and maintain until test end

Record flame propagation, temperature, and FSI using the thermocouple and data acquisition system.

Total test duration is 20 minutes. Upon completion, safely remove the sample and review results.

Maintenance Information

Regularly clean the combustion chamber and burners to ensure consistent heat flux.

Calibrate thermocouples and power output control systems periodically.

Inspect sample holders and chamber integrity before each test.

Ensure gas supply is stable and leak-free.

Maintain ambient temperature between 10–35°C for consistent testing conditions.
