Developed by the Federal Aviation Administration (FAA), the “DOT/FAA/AR-00/12 Aircraft materials fire test manual” is designed to ensure the accuracy and relevance of the fire test methods mandated by the FAA for aircraft materials and consists primarily of the following sections:
This test method is designed to be used to determine the flame resistance of materials when tested in accordance with the 60-second and 12-second vertical Bunsen burner tests specified in Federal Aviation Regulations (FAR) 25.853 and FAR 25.855.
This test method is intended for use in determining the resistance of materials to flame penetration and flame and glow propagation when tested in accordance with the 30-second, 45-degree Bunsen burner test specified in FAR 25.
This test method is designed for use in determining the flame resistance of materials when tested in accordance with the 15-second horizontal Bunsen burner tests specified in FAR 25.853.
This test method is designed to be used to determine the flame resistance of electrical wire insulation when tested in accordance with the 30-second, 60-degree Bunsen burner test specified in FAR 25.869.
This test is designed to be used to determine heat release rates to demonstrate compliance with the requirements of FAR 25.853. The heat release rate is measured throughout the test period from the time the sample is injected into the controlled exposure chamber and includes the time for surface ignition and gradual flame retention.
This test method is used to determine the smoke generating characteristics of aircraft passenger cabin interior materials to demonstrate compliance with the requirements of FAR 25.853.
This test method evaluates the burn resistance and weight loss characteristics of aircraft seat cushions when exposed to a high-intensity open flame to demonstrate compliance with FAR 25.853 requirements.
This test method evaluates the flame penetration resistance capabilities of aircraft cargo bay lining materials using a high-intensity open flame to demonstrate compliance with FAR 25.855 requirements.
This method is used to demonstrate compliance with technical standard order C69A.
These methods are designed to determine the fire-retention capacity of containers, carts, and compartments used to store flammable waste materials in accordance with the requirements of FAR 25.853. The component construction used in the top, bottom, and sides of these compartments must meet the requirements of FAR 25.853 and FAR 25.855. This specification addresses multiple test arrangements: entry carts, food carts, waste carts, and waste compartment meal bins.
This test method is used to determine the fire resistance of high-temperature hose assemblies used in designated fire zones to demonstrate compliance with Technical Standard Orders C42, C53A, and C75 against damage due to flame and vibration. The requirements and procedures for this test method vary depending on the hose materials and the hose assembly application.
This test method is intended to determine the ability of components and structures to control the transmission of fire or its effects to power unit (engine) compartments, thereby preventing additional hazards to the aircraft. This test is used to demonstrate compliance with FAR 25.867, 25.865, 25.1191, and 25.1193.
This test method is designed to determine the resistance to damage due to flame and vibration of high-temperature electrical connectors used in fire areas according to the requirements of FAR 23.1192, 25.1191, 27.1191, 29.1192, 25.863, 25.865, 25.867, 25.1201, and 25.1203. This test is used to evaluate the ability of wired, electrical, and firewall connectors to prevent flame transmission to the protected side of the firewall. This test provides a means of evaluating the ability of connectors to sustain a minimum current of 1 A for a limited period. It is recommended that each connector type be tested in three sizes: 22-19, 14-7, and 12-3. Each connector size is tested separately.
This test method is designed to determine the resistance to flame and vibration damage of high-temperature electrical wires used in designated fire zones according to the requirements of FAR 25.863, 25.865, 25.867, 25.1201, 25.1203, and 25.1359. This test method generally follows MIL-W-25038E. The method is primarily used in the United States and by most wire and cable manufacturers. ISO/DIS 2685.2 is a similar test procedure.
This test method provides certification test procedures for the repair of damaged cargo liners, including roof and sidewall liners, pressure cylinder head liners, fabric liners, and bulkhead separator liners. Repairs should not be performed in areas of the cargo liners designed to resist explosion in the event of depressurization. Repairs typically involve patches of fiberglass-reinforced material bonded to the cargo liners to seal tears, ruptures, and punctures resulting from abrasion, abuse, and accidents. The patches are usually coated with an intumescent material to prevent separation during heat exposure. Because of the numerous types of damage that can occur in cargo liners, the following test procedures are intended to ensure that any repair will safely contain a cargo compartment fire. Soft or neoprene-coated fabric liners, commonly used as bulkhead separators, should also be included in this category, and the same test procedures should be followed when repairs are made as for conventional liners.
This test method is used to determine the flame resistance of blankets tested in a horizontal position and exposed to a Bunsen burner for 12 seconds.
This test method is used to determine the smoke generation characteristics of insulated aircraft wire using a smoke density chamber.
Dry arc tracking testing of wire insulation provides a comparative assessment of insulation degradation and arc propagation when wires within a bundle are exposed to an electric arc. This test method is used to obtain comparative data.
Dry arc propagation resistance testing for wire insulation allows evaluation of an insulation's ability to resist damage in an electric arc environment. In service, electric arcs can be caused by a variety of factors, including insulation degradation, improper installation, and friction. It has been documented that the results of an arc propagation test can vary slightly depending on the arc initiation method. Therefore, a standardized test method should be selected to evaluate the overall arc propagation resistance properties of an insulation.
This non-regulatory, industry screening test is designed to determine the resistance of thermal acoustic insulation films to flame propagation when tested with alcohol-soaked cotton swabs.
