Test Procedures

I. Equipment Installation and Preparation

Accessory Check: Confirm that the included accessories include the sample holder, positioning device, drip tray, flame ruler, gas valve, and gas pipe. If a wind speed device is selected, an additional power supply needs to be connected, and the wind speed should be adjusted to 0.7 ± 0.1 m/s.

Gas and Power Connection: Install the valve onto the gas cylinder (the safety valve needs to be opened manually), and connect the equipment's power and gas supply. If a wind speed meter is equipped, calibrate the airflow direction and insert it into the temperature measurement port.

II. Operating Procedure

Parameter Settings: Set the experiment time (usually 15 seconds or 30 seconds) via the touchscreen interface, and select whether to enable the "automatic ignition" or "automatic gas shut-off at the end of the experiment" function.

Sample Installation: Use the sample holder to fix the material (usually 250mm × 90mm), and adjust the flame contact position using the positioning device (e.g., 40mm from the bottom edge).

Flame Adjustment: Start the gas and ignite the flame, adjust the Bunsen burner to a 20 ± 2mm blue flame, and tilt it 45 degrees towards the sample.

III. Experiment Execution and Observation

Start Experiment: After clicking "Start," the burner contacts the sample and the countdown begins. Observe the combustion phenomena (e.g., surface ignition, burning to the marked line).

Data Recording: Save the data after the experiment, turn off the gas, and check the sample's combustion status (e.g., remaining length, whether dripping material ignites the filter paper).

IV. Safety and Maintenance

Operating Procedures: Avoid putting hands into the test furnace, and do not stack flammable materials around the equipment. Stop the machine immediately in case of any abnormalities.

Regular Calibration: Calibrate the heat load uniformity (4-point temperature difference ≤ 15℃) and wind speed (5-point measurement error ≤ 10%) every 3 months.
