【Scope of application】: The time for the Bunsen lamp to apply flame to the specimen is adjustable, and the ignition of the Bunsen lamp adopts the electronic ignition method for fast and reliable ignition. MF-1 safety helmet flame retardant performance test device, mainly used to test the flame retardant performance of hard hats. [Meet the standard.]】:It is developed according to the main technical parameters of the national standard GB/T2812. [Instrument characteristics】: 1. Electronic ignition. 2. Automatic timing positioning of the burner. 3. The ignition time is arbitrarily set from 0 to 99.9 seconds, and the retinuation time and smoldering time are automatically recorded and digitally displayed. 4. The flame height can be adjusted, and there is a flame height gauge to measure the flame height to assist in setting the flame height, and the flame temperature measurement device is configured. 5. “Push-pull” sample frame fixing device, “positioning wire” and “guide rail” auxiliary positioning. 6. Equipped with a highly sensitive combustible gas leakage alarm device, if a combustible gas is found, it will automatically cut off the gas. 【Technical parameters】: 1. Bracket: can firmly clamp the safety helmet to ensure a stable position in the test, and can be moved to adjust the distance between the safety helmet and the flame jet head. 2. Timer: The value error is ±1%, which is used to record the reignition time, accurate to 0.01s. 3. Timer: the value error is ±1%, used to determine the time when the flame is applied to the hard hat, the burning time can be set by yourself, the Bunsen lamp can be removed by itself after the flame is completed, and the igniter timing range: 0-999.9 seconds. 4. Flame height measurement device: the height of the ruler is 50mm. 5. Flamethrower head: horizontally placed fuel nozzle, inner diameter 10mm. 6. Fuel supply device: pressure regulating valve, air volume regulating valve, and gas storage tank device can ensure that the flame jet head stably ejects 50mm long blue flame. 7. Box: The box is large enough to ensure that the test is not affected by the wind. 8. Power supply voltage and power: 220V±10%, 50HZ, power about 100W. 9. The inner diameter of the Bunsen lamp is 10mm±0.10mm. 10. Gas source: methane, propane, butane, petroleum liquefied gas.Note: The air source and link header users are self-provided. 11. Ambient temperature: -10°C-30°C. 12. Relative humidity: ≤85%.
