Scope of Application

【Operating Instructions】

The duration of the flame applied to the specimen by the Bunsen burner is adjustable, and the burner ignition utilizes a quick and reliable electronic ignition method. The MF-1 Safety Helmet Flammability Test Apparatus is primarily used to test the flammability resistance of safety helmets.

YS-106 Safety Helmet Flammability Test Apparatus

Applicable Scope:
The duration of the flame applied to the specimen by the Bunsen burner is adjustable, and the burner ignition utilizes a quick and reliable electronic ignition method. The MF-1 Safety Helmet Flammability Test Apparatus is primarily used to test the flammability resistance of safety helmets.

Compliance Standards:
It is developed based on the main technical parameters of the national standard GB/T 2812.

Instrument Features:

1. Electronic ignition.

2. Automatic timed positioning of the burner.

3. Ignition time is arbitrarily settable from 0 to 99.9 seconds. Afterflame time and afterglow time are automatically recorded and digitally displayed.

4. Flame height is adjustable. A flame height ruler is provided to assist in setting the flame height, and a flame temperature measuring device is included.

5. "Push-pull" specimen holder fixing device, assisted by "positioning wires" and "guide rails" for accurate positioning.

6. Equipped with a highly sensitive combustible gas leak alarm device. If combustible gas is detected, it will alarm and automatically cut off the gas supply.

Technical Parameters:

1. Bracket: Capable of firmly clamping the safety helmet to ensure a stable position during the test. It is movable to adjust the distance between the safety helmet and the flame nozzle.

2. Timer: Indication error ±1%, used to record the afterflame time, accurate to 0.01s.

3. Time Setter: Indication error ±1%, used to determine the duration the flame is applied to the safety helmet. The burning time can be self-set. After the flame application is complete, the Bunsen burner can automatically retract. Igniter timing range: 0-999.9 seconds.

4. Flame Height Measuring Device: Ruler height is 50mm.

5. Flame Nozzle: A horizontally placed fuel nozzle with an inner diameter of 10mm.

6. Fuel Supply Device: Includes a pressure regulating valve, gas flow regulating valve, and gas storage tank device, ensuring the flame nozzle stably emits a 50mm long blue flame.

7. Chamber: A sufficiently large chamber to ensure the test is not affected by wind.

8. Power Supply and Power: 220V ±10%, 50Hz, power approx. 100W.

9. Bunsen Burner Inner Diameter: 10mm ±0.10mm.

10. Gas Source: Methane, Propane, Butane, Liquefied Petroleum Gas (LPG). Note: The gas source and connection fittings are to be supplied by the user.

11. Ambient Temperature: -10℃ to 30℃.

12. Relative Humidity: ≤85%.
