FAR.25.853 Vertical Flammability Test Equipment for Aircraft Material

Introduction:

The vertical flammability test equipment is designed according to Federal Aviation Regulation Sec. 25.853 and CCAR-25 Appendix F of the first part b (4), b (6), b (7) .Equipment integrated appendix F the first part b4 vertical combustion and b 6 45 ° and 60 ° b7 item combustion demand for housing and design ;And b2 is the request of the sample holder and customized for various experiment using the sample holder and corresponding independent test procedure;

This flammability test equipment is designed with touch screen control system and PLC, it can make the experiment more automaticly and easier to extract data; and provide the combustion at the angle of 90°, and 45 °60 ° with independent test procedures;

Standard:

• CCAR-25 Appendix F of the first part of b 4 and 6,7 items
• FAA.FAR.25.853 American Airlines management organized - transport aircraft - cabin interior of standards

Feature:

1.The tank is painted and equipped with viewing window;

2. The chamber dimensions: 800mm x 450mm x 640mm;

3. The vertical flammability testing equipment has function of automatic electronic ignition;

4. Ignition timing can be arbitrarily set around 0 ~ 99.99 seconds, continued burning time and flame time can be automatically recorded and digitally displayed;

5, The flame height can be adjusted;

6. The "push-pull" fixture;

7. The burner is located at the sliding track, easily operated, when pushed to the combustion position, automatic timing.

8. Needle valve can precisely control the gas flow and adjust standard flame height around 38.1mm;

9. According to the test samples, multiple samples holder can be chosen; customizing BWF sample size and sample holder.

10. Brand pressure gauge and pressure regulator can accurately adjust the gas pressure;

11. Bunsen burner tube inner diameter is 9.5mm; the bottom of sample must be higher than the light of 19.1mm

12.Thermocouple can test the maximum flame temperature about 1000 ℃; flame kerne temperature must be higher than 843 ℃

13.The ignition time can be set freely and the buzzer can remind people when the time is over;

14. PLC microcomputer control system with touch screen can make the experimental process more automaticly and the data can be automatically recorded and stored;
