DIN 54837 Burning Behaviour Testing Machine For Railway

Instrument introduction:

The DIN 54837 large combustion box is based on the method determined by the DIN 54837 standard of the Rail Vehicle Standards Committee of the German Institute for Standardization (FSF). , Determine the length of the sample destroyed by the flame, the time to complete combustion, the development of smoke and the combustion characteristics of the drippings.
Passing the DIN 54837 standard test helps to classify products according to DIN 5510-2 for flammability, smoke formation and dripping characteristics.
It is suitable for flammability grades S2 to S5; smoke density grades SR1 and SR2 (light attenuation integral); droplet status ST1&ST2.

main feature:
1. Large combustion test box, equipped with double transparent observation windows, in line with standard DIN 50050-2;
2. The internal size of the box is 1350 X 800 X 800mm, and the overall height of the combustion box is 3.2 meters;
3. The bottom of the box body is a stainless steel square grille, which can be evenly and naturally ventilated. The size of the grille is 30 X 30mm and the height is 30mm;
4. Equipped with anemometer to measure wind speed, the range is 0-10m/s, and the accuracy is 0.1m/s;
5. Combustion test box, three K-type thermocouples are installed in the exhaust pipe, the measurement range is 0-300 degrees, and the accuracy is 0.1 degrees;
6. Digital display temperature display instrument, which can display the average temperature of 3 thermocouples in the exhaust pipe, with an accuracy of 0.1 degrees;
7. The base of the test box is 800 X 800 X 800 mm;
8. Install 6 time counters, which can separately record the ignition time, smoldering time, continuous burning time, maximum flame height time, dripping occurrence time and burning time, and the accuracy of the counter is 0.1 second;
9. Equipped with a stainless steel calibration plate, 3 K-type thermocouples are welded on the back, the temperature range is 0-900 degrees, used to calibrate the flame temperature of the burner;
10. Equipped with 3 temperature display instruments, which can display the three-point calibration temperature on the calibration board with an accuracy of 0.1 degrees;
11. Equipped with wide-mouth burner device and manual sliding track;
12. Equipped with 3 stainless steel sample holders, which can be hung on the sample rack;
13. Equipped with smoke density measurement system, including incandescent light source and silicon photodiode;
14. The incandescent lamp is a 2896K light source;
15. The silicon photodiode is equipped with a cosine calibration device and a color filter, which has a high degree of human eye matching;
16. Equipped with a data acquisition system, using a 232 communication interface, which can be connected to a computer. The test software can display the transmittance value and the absorbance value, and can draw a standard transmittance curve at the same time.
