Product Details
Burn Through Test Apparatus
Brief Introduction
The Burn-Through Test Apparatus delivers precise fire-barrier data to verify how effectively insulation materials delay or stop flame penetration.
Highlights / Outstanding Features / Characteristics
- Realistic Flame Penetration Simulation: Exposes aircraft or structural thermal-acoustic insulation to a controlled, high-intensity heat source to test its definitive burn-through threshold.
- Real-Time Material Diagnostics: High-precision sensors capture continuous data on physical material degradation, structural integrity, and char layer formation.
- Advanced Data Acquisition: Built-in software monitors and logs performance metrics instantly, ensuring flawless data tracking for regulatory audits.
- Safety & Compliance Focused: Designed specifically to help manufacturers certify that their insulation products meet strict aviation, marine, or commercial building fire codes.
Description
In compliance with:
- US Federal Aviation Regulations FAR25
- Civil Aviation Administration of China transport aircraft standard CCAR-25-R4
Main parameters
Laboratory:
The length and width of the laboratory floor should not be less than 3.05m.
Burner:
- Structure of the Burner:
- It is an improved gun-type burner. The setting of the burner determines the flame characteristics, and parameters such as fuel pressure, nozzle depth, slator position, and inlet air flow must be properly adjusted to achieve the proper flame.
- Nozzle:
- The nozzle should maintain fuel pressure to produce a nominal fuel flow of 0.378l/min.
- Conical Tube of Burner:
- The extended cone of the burner is installed at the end of the ventilation pipe, and its length is (305±3) mm. The burner cone should have an opening with a width of (280±3) mm and a height of (152±3) mm.
Installation of Heat Flow Meter:
It is installed on a heat insulation board with a length of (305±3) mm, a width of (152±3) mm, and a thickness of (19±3) mm. The plate is fastened to the angle bracket and placed on the specimen holder when calibrating the burner.
Meter:
It measures and records the output value of the heat flow meter and thermocouple with a recording potentiometer of suitable range or other suitable calibrated material.
Timing Device:
It uses a stopwatch or other timing device to measure the action time and burn-through time of the burner flame, and its accuracy is ±1.5s/h.
Laboratory Tests:
Tests are conducted in a laboratory to reduce or eliminate the possibility of fluctuations in test data due to air movement. The length and width of the laboratory floor should not be less than 3.05m.
