Combustion Testing Machine For Non-Metallic Materials Of Aviation

What is the Combustion Testing Machine For Non-Metallic Materials Of Aviation？

It is suitable for the combustion performance test of non-metallic materials in the aircraft cabin:

Inner cabins containing crew or passengers: such as ceilings, inner siding, partitions, galley structures, large cupboard siding, decking of structural floors and floor coverings, textiles (including curtains and coverings), seat cushions, Liners, coated fabrics (decorative and non-decorative), leather goods, trays and galley equipment, electrical bushings, air ducts, joints and edge coverings, Class B and E cargo or luggage compartment liners, Class B, C, D or E cargo or luggage compartment floors, cargo covers and clear covers, moulded and thermoformed parts, air duct joints and trim strips (decorative and abrasion resistant), etc.;

Cargo and luggage compartments that do not carry crew or passengers such as: insulation blankets and cargo shields, tethering equipment for each cargo and luggage compartment (including containers, ordinary boxes and pallets), etc.

Compliance：

FAR25.853 "FEDERAL AVIATION ADMINISTRATION, DEPARTMENT OF TRANSPORTATION SUBCHAPTER C -- AIRCRAFT PART 25 -- AIRWORTHINESS STANDARDS: TRANSPORT CATEGORY AIRPLANES";

CCAR-25-R4.853 "China Civil Aviation Regulations Part 25 Airworthiness Standards for Transport Class Aircraft" Appendix F Part I standard requirements;

HB5469-2014 "Burning test method for cabin interior nonmetallic material of civil aircraft";

HB5470-2014 "Requirements of burning performance for carbin interior nonmetallic material of civil aircraft";

RTCA/DO-160G "Environmental Conditions and Test Procedures for Airborne Equipment-User's Guide Chapter 26" G26.6.2, G26.6.3, G26.6.4 standards.

Main performance parameters:

1. Test type: divided into four categories: vertical burning test, horizontal burning test, 45° burning test; 60° burning test.

2. Instrument composition: it consists of three parts, the combustion box, the control part, and the test device;

3. Combustion box:

3.1 The vertical combustion test, the horizontal combustion test and the 45° combustion test share one box; the 60° combustion test is an independent combustion box.

3.2 The front of the box is provided with a tempered glass observation window sealed during the test, which is convenient for observing the test situation.

4. Burning torch:

4.1 Bunsen burner is used, the inner diameter of the nozzle: Ф9.5±0.1mm, the nozzle: Ф0.9±0.03mm, and the height of the nozzle from the air inlet is 100±10mm. a total of two;

4.2 Torch angle: 0°, 45°, 60°, 90° can be adjusted;

4.3 Flame height: 20mm~100mm can be adjusted arbitrarily. Adjust flame height according to different test types.

5. Timer: burning time, flame burning time, smoldering time, dripping flame burning time. Timing accuracy 0.1S, timing range: 0~99.99s/m/h can be set;

6. Length gauge: resolution 1.0mm;

7. Temperature measurement system:

7.1 Thermocouple: K-type thermocouple with a diameter of 1.2~1.5mm;

7.2 Temperature instrument: It is a hand-held thermometer with a range of 0~1000°C and a resolution of ≧1°C;

7.3 Equipped with an electronic stopwatch: accurate to 0.1S (backup during temperature measurement and calibration);

8. Specimen fixture: made of stainless steel, divided into horizontal test frame, vertical test frame, 45° test frame and 60° test frame;

9. Gas: use methane with a concentration of not less than 99%;

10. Power supply: AC220V, 500W;

11. Use space: length 1600mm, width 650mm, height 850mm;

12. Smoke and dust emission: excluding fume hood, it is an optional accessory.
