Aircraft Thermal Acoustic Insulation Tester
Aircraft Thermal Acoustic Insulation Tester — ToronFT™ ATC
ToronFT™ ATC Aircraft Thermal Acoustic Insulation Tester is a high-precision fire safety testing instrument designed to evaluate the burn-through resistance of thermal and acoustic insulation materials under high-intensity open flame exposure. Based on US Federal Aviation Regulations FAR 25 requirements, the ToronFT™ ATC provides the standardized, controlled flame exposure environment and precision heat flux measurement infrastructure required for aircraft fuselage insulation material certification — ensuring that thermal and acoustic insulation used in transport aircraft can withstand post-crash fire conditions without burn-through.
The burn-through resistance tester features a foil-type Gardon total heat flow density meter (range 0–22.7 W/m², accuracy ±3% of indicated reading), a 16-bit high-precision control board with microcomputer management, real-time result display with dynamic curve plotting, and comprehensive safety protection — all integrated into a system with reasonable structure, stable performance, and easy operation that fully meets the demanding requirements of aviation authority approval programs.

- Safety protection system: power overload protection, short circuit protection, and control loop overload protection — three independent safety layers
- 16-bit high-precision board + microcomputer control: stable performance, reasonable structure, and easy operation
- Real-time result display: measurement results shown in real time during the test; dynamic curve drawn continuously throughout the event
- Data management: permanently saveable data; data retrieval and printing; report generation directly from the instrument
- Compliant with US FAR 25 the primary US aviation burn-through resistance test standards
Theory and Method
Burn-through resistance testing evaluates the ability of thermal and acoustic insulation materials to prevent the passage of an open flame from one side to the other — simulating a post-crash fire scenario in which a fuselage fire attempts to penetrate the insulation blanket to reach the aircraft cabin interior. The test exposes one face of the insulation specimen to a high-intensity open flame for the defined test duration, while the heat flux transmitted through the specimen is continuously monitored on the unexposed face using the Gardon-type total heat flow density meter.
The ToronFT™ ATC heat flow meter calibration uses a foil-type Gardon heat flow meter as the back heat flow meter (shareable between front and back positions), with a measuring range of 0–22.7 W/m² and an accuracy of ±3% of the indicated reading. During the test, measurement results are displayed in real time and a dynamic performance curve is plotted continuously, providing a complete picture of the heat flux transmission profile throughout the burn-through test event. The 16-bit high-precision board and microcomputer control system ensure accurate, stable performance with data that can be permanently saved, retrieved, printed, and compiled into test reports directly from the instrument.
