DX8221 Helmet Flame Retardant Performance Test Device

Product Specification

DX8221 helmet flame retardant performance test device

Meet the standards: GB/T 2812-2006 "Test Methods for Safety Helmets" and GB/T 2811-2007 "Safety Helmets" in the flame retardant performance test standards for safety helmets. It is mainly used for testing the flame retardant performance of safety helmets, and is widely used in safety helmet manufacturers, major quality inspection units and construction engineering testing stations.

Test method: The helmet flame retardant performance tester test should be carried out in a fume hood, and the helmet after the high temperature impact test should be clamped on the bracket in the direction of normal wearing, so that the side of the cap shell is aligned with the flamethrower head, and the axis of the flamethrower head should be adjusted to pass through the axis of the cap shell and be 50mm±1mm above the edge of the cap shell to avoid the ventilation hole; Adjust the position of the bracket so that the distance between the test area of the helmet and the end face of the flamethrower is 45mm±1mm, and then move away; Open the gas volume control valve, adjust the flame length to 50mm±2mm, and ensure that the flame has at least 15mm blue flame; Move the bracket to the position determined in front and the flame acts on the cap shell for 10s, cutting off the air source. The continuous combustion time and possible penetration phenomenon are recorded with an accuracy of 0.1s.

Specifications:

1. Bracket: It 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 flamethrower.

2. Timer: The indication error is ±1%, which is used to record the refueling time, which is accurate to 0.01s.

3. Timer: The indication error is ±1%, which is used to determine the time when the flame is applied to the helmet, and the burning time can be set by yourself, and the Bunsen burner can be removed by itself after the flame is completed, and the ignition timing range: 0-999.9 seconds.

4. Flame height measuring device: ruler height 50mm.

5. Flamethrower: Horizontally placed fuel nozzle with an inner diameter of 10mm.

6. Fuel supply device: pressure regulating valve, gas volume regulating valve, air storage tank device, which can ensure that the flame sprinkler head stably sprays a blue flame with a length of 50mm.

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 Bunsen burner is 10mm±0.10mm.

10. Gas source: methane, propane, butane, petroleum liquefied gas (provided by the user).

11. Ambient temperature: -10°C—30°C.

12. Relative humidity: ≤85%.

Instrument features

1. Electronic ignition; The burner is automatically timed and positioned.

2. The ignition time is set arbitrarily from 0 to 99.9 seconds, and the continuous ignition time and smoldering time are automatically recorded and digitally displayed.

3. 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.

4. "Push-pull" sample frame fixing device, "positioning wire" and "guide rail" to assist positioning.

5. Equipped with a highly sensitive combustible gas leakage alarm device, if a combustible gas is found, it will alarm and automatically cut off the gas.
