Test Procedure
Install the sample and adjust the burner angle.
Adjust the O₂/N₂ flow rate to the initial concentration (e.g., 18% or 25%).
Ignite the sample and record the burning time or flame front position.
Adjust the oxygen concentration based on the burning behavior, and repeat the test until the accuracy requirements are met (the difference between three test results < 0.5%).
Result Analysis: Calculate the average of the three oxygen concentrations to determine the LOI value of the material.
Safety Precautions
Personal Protective Equipment: Operators must wear safety glasses and gloves to avoid injury from smoke or flames.
Gas Management:
The purity of the oxygen cylinder must be calibrated regularly, and the nitrogen cylinder pressure should not be less than 1MPa.
Adjust the flow rate evenly to avoid sudden changes in gas pressure.
Equipment Maintenance:
Regularly clean the combustion tube and igniter, and remove combustion residue.
If any problems occur, please contact professional personnel for repair; do not disassemble components yourself.
Ventilation Requirements: The test must be conducted in a fume hood to prevent the accumulation of exhaust gases.
Maintenance Information
(1) Clean the combustion tube and igniter regularly to remove residue.
(2) Inspect oxygen and nitrogen cylinders for proper pressure and purity.
(3) Avoid disassembling critical components; contact professional personnel for repairs.
(4) Ensure proper ventilation to avoid accumulation of exhaust gases.
