Product Introduction
Fire helmet fire-resistant combustion test device is developed according to NFPA 1971-2007 test standard. Its test principle is that under the action of thermal radiation, open fire impacts on various components of fire helmet, and then detects its flame-retardant performance.
Performance characteristics
1. The radiation heat source is steel heating pipe. The temperature
of heating pipe can be adjusted by using PID temperature control
mode, so as to adjust the heat radiation flux. The heat radiation
flux can be controlled in the range of 10 kW/m2+1 kW/m2, and the
heat radiation flux can be accurately adjusted to 0.1 kW/m2.
2. Imported water-cooled heat flow meter is used to monitor the
heat radiation output flux. The measuring range of water-cooled
heat flow is 0-50kW/m2.
3. Equipped with self-circulating cooling water device, the surface
temperature of water-cooled heat flowmeter can be taken away to
achieve protection function.
4. Provide secondary instruments to display the value of heat
radiation flux.
5. The burner is a lamp device with a nozzle diameter of 13 mm+3
mm.
6. Provide gas secondary decompression device to provide stable gas
pressure;
7. By adjusting the gas flow rate with a rotor flowmeter, the flame
temperature can be controlled in the range of 1100 ~1300 C.
8. A K-type thermocouple is equipped to measure the temperature at
the tip of the inner flame and provide a secondary instrument to
display the flame temperature value.
9. Equipped with time relay, the test time of burning flame of
Bunsen lamp can be controlled for 15 seconds.
10. Equipped with time timer, it can record the duration of flame
continuation of cap and shell.
11. The radiation source is shielded by pneumatic baffle to avoid
the radiation test sample. When the test begins, it opens
automatically and closes automatically after the test ends.
12. The radiation heat source radiates directly to the top of the
helmet, and the height of the specimen can be adjusted.
13. Equipped with a metal head die that meets the average
requirement of GB/T 2428-1998 "Adult Head and Face Size";
14. The metal die is installed in the test cabin and the height can
be adjusted manually.
15. Metal die can adjust left and right position by Y axis.
16. The height of the Bunsen lamp device can be adjusted manually
according to the height of the helmet when it is placed at 45
degrees.
17. The burner can be moved to the middle part of the high point of
the helmet and automatically cut off the combustion gas source
after 15 seconds.
18.The combustion area is equipped with closed tempered glass
observation door, which can be used for the tester to observe the
test process and avoid the interference of external gas flow.

What is fire according to NFPA?
Description. Class A Fires. Fires in ordinary combustible materials, such as wood, cloth, paper, rubber, and many plastics. Class B Fires. Fires in flammable liquids, combustible liquids, petroleum greases, tars, oils, oil-based paints, solvents, lacquers, alcohols, and flammable gases.
How does fire retardant work?
Fire retardant contains salts (typically fertilizers) that alter
the way wildfires burn, decreasing fire intensity and slowing the
advance of the fire, even after the water in the fire retardant has
evaporated. The water in long-term fire retardants serves primarily
to aid in uniform dispersal of the chemical over the target area.
