Test Procedures
Sample Installation: Secure the non-metallic material sample on the corresponding fixture (horizontal, vertical, or inclined).
Parameter Setup: Adjust burner angle, flame height, and timing according to the test standard.
Ignition: Activate Bunsen burner; ensure flame contacts the sample at the correct height.
Timing and Observation: Monitor the combustion process through the tempered glass observation window, using multi-phase timing for burning, dripping, and smothering phases.
Data Recording: Record temperatures, flame duration, and material behavior using thermocouples, calipers, and the timing system.
Analysis: Evaluate flame spread, material performance, and compliance with FAR25.853. CCAR-25-R4.853. and related standards.
Post-Test: Remove sample, clean chamber, and reset the system for the next test.
Conclusion
This tester provides a reliable and standardized method to assess the flame retardant properties of aircraft cabin non-metallic materials. Its modular design, precise timing, adjustable burners, and observation capabilities ensure repeatable and safe testing compliant with international aviation safety standards.
