Flammability Test

Flammability testing is required for materials used in the construction of compartment interiors and cargo / baggage compartments of all transport category aircraft, per 14 CFR 25.853 & 25.855 for airplanes or 29.853 & 29.859 for rotorcraft.

The materials must be tested in accordance with these regulations and the guidance and test methods included in part 1 of Appendix F to Part 25. The testing required varies based on the criteria of where the material is installed and the function of the material.

Av-DEC FR products are tested to and pass the 12 second vertical burn test method, which is a more stringent test than the 15 second horizontal test method. According to FAA Policy Statement for "Flammability Testing of Interior Materials", PS-ANM-25.853-01- R2. Vertical Bunsen burner test data will substantiate configurations that only require horizontal Bunsen burner testing.

Av-DEC HI-TAK® PRS® 12-Second Vertical and 15-Second Horizontal Burn Tests

Av-DEC's Flame-Retardant HI-TAK Polyurethane Rolled Sealants (PRS) pass the 12-second Vertical Bunsen Burner Test per 14 CFR Part 25, Appendix F, Part 1 (a)(1)(II) and the 15-second Horizontal Bunsen Burner Test per 14 CFR Part 25, Appendix F, Part 1 (a)(1)(IV) & (V). The 12-second vertical flammability test is one of the more stringent forms of flammability testing conducted on cabin and cargo materials. Each lot of Av-DEC Flame-Retardant sealant is tested using the vertical Bunsen burner method and the results are approved by an FAA Designated Engineering Representative.
