CCAR-25 FAR 25.853 Vertical Flammability Tester
Product information
CCAR-25/FAR 25.853 Vertical Flammability Tester is a professional fire testing instrument designed specifically for aviation interior materials. It fully complies with CCAR-25, FAR 25.853 Appendix F Part I, CS-25, Airbus AITM 2.0002, and Boeing BSS 7230 standards. Equipped with a precision Bunsen burner, automatic timing system, and standardized specimen holder, it accurately performs 12-second and 60-second vertical burn tests to evaluate flame spread length, after-flame time, and drip characteristics of aircraft cabin materials. Widely used for testing seat upholstery, wall panels, ceiling panels, carpets, cargo compartment liners, curtains, and other interior components, this tester is an essential tool for aircraft manufacturers, material suppliers, and certification laboratories to ensure compliance with global aviation fire safety regulations.

Product Application
The CCAR-25 Aircraft Vertical Flammability Tester is primarily used to evaluate the fire resistance of materials in aircraft cabins and cargo holds. The testing scope covers all materials exposed to passenger or crew areas. The following is the testing scope down to the individual product level (based on FAR 25.853(a) classification and Appendix F testing requirements):
Interior Ceiling Panels: Composite or fabric panels used for cabin ceiling coverings.
Interior Wall Panels: Cabin bulkhead trim panels, including sound insulation layers.
Partitions: Cabin partition walls, such as those separating business class from economy class.
Galley Structure: Galley cabinets and insulation panels.
Large Cabin Walls: Outer shell panels for overhead bins or storage compartments.
Structural Flooring: Main cabin floor panels, including the underlayment for carpets.
Overhead luggage rack materials: Plastic or composite material linings for overhead luggage racks (excluding under-seat storage).
Seat cushions and upholstery: Seat fabric, foam padding, and overlays.
Floor coverings: Cabin carpets or non-slip mats.
Decorative and non-decorative coated fabrics: Wall or seat upholstery fabrics.
Leather: Natural or synthetic leather used for seats or upholstery.
Trays and galley furnishings: Tray holders or galley accessories.
Electrical conduit: Cabin wiring conduit.
Air ducting: Lining material for ventilation ducts.
Joint and edge coverings: Panel joint seals.
Liners for Class B and E Cargo Compartments: Cargo compartment bulkhead linings.
Floor Panels for Class B, C, E, and F Cargo Compartments: Cargo compartment floors.
Cargo Covers: Cargo securing netting or curtains.
Transparencies: Transparent plastic sheets for windows or bulkheads.
Moulded and Thermoformed Parts: Injection-molded interior fittings, such as handles or brackets.
Air Ducting Joints: Duct connection seals.
Trim Strips - Decorative and Chafing: Edge trims or chafing strips.
These products must pass a vertical test (flame application for 12 or 60 seconds) to ensure a burn length <203 mm, afterflame <15 seconds, and no dripping combustion.
