Safety helmet flame retardant testing machine

summary
This testing machine is mainly used for determining the flame retardant performance of safety helmets
Compliant with standards
Developed based on the main technical parameters of the national standard GB/T2812.
technical parameter
1.Environmental temperature: -10 ℃ -30 ℃
2. Relative humidity: ≤ 85%
3. Power supply voltage and power: 220V ± 10%, 50HZ, power of approximately 100W
4. The inner diameter of the lamp is 10mm ± 0.10mm
5. The burner will automatically move away after the completion of the flame application
6. Timer: display error ± 1%, used to record the ignition time, accurate to 0.01s
7. Timer: with an indication error of ± 1%, it is used to determine the time for the flame to be applied to the safety helmet. The combustion time can be set by oneself. After the flame is applied, the ignition lamp can be moved away by itself. The timer range of the igniter is 0-99.9 seconds
8. Flame height measuring device: ruler height 50mm
9. Flame jet nozzle: horizontally placed fuel nozzle with an inner diameter of 10mm
10. Fuel supply device: pressure regulating valve, gas volume regulating valve, gas storage tank device, can ensure that the flame spraying head can stably spray a blue flame of 50mm length
11. Gas source: methane, propane, butane, liquefied petroleum gas
