The Vertical Flammability Test Chamber is a test chamber in which one end of a rectangular strip specimen is fixed on a horizontal or vertical fixture and the other end is exposed to a prescribed test flame to evaluate the burning behavior of the specimen by measuring the linear burning rate; the vertical burning behavior of the specimen is evaluated by measuring the remaining flame and afterglow time, the range of burning and the dropping of burning particles. The vertical combustion behavior of the specimens was evaluated by measuring the remaining flame and afterglow time, combustion range and burning particle dropping.
 

10 Common Myths About Vertical Flammability Test Chamber:

1、Check whether the power supply voltage meets the equipment requirements before use.
 
2、Check carefully whether there is gas leakage from the gas pipe and joints before starting the machine, and confirm that it is normal before conducting the test operation.
 
3, Vertical Flammability Test Chamber test samples, some materials will release toxic and harmful gases, it is recommended that the test should be carried out in the fume hood, and good human protection.

4, the test in the fume hood, after each test to discharge the gas generated by the test process and other combustible gases, replace the fresh air. 5, the test process to take precautions to reduce the fume hood ventilation during the test, you can check the ventilation through the flue ventilation equipment.
 
6, at the end of the test, first close the gas main valve, burning despite the combustible gas inside, and then turn off the power supply to confirm that the combustion material is completely extinguished before leaving the operating site.
 
7, the instrument is equipped with a gas alarm device, if the gas alarm sounds, please check whether there is a gas leak. The gas alarm should be turned off immediately after the gas alarm and the gas source, and then restarted after troubleshooting.
 
8, Vertical Flammability Test Chamber should use the specified voltage, the instrument should have a grounding wire for electricity.
 
9, instruments, gas storage, as well as the operation of the place should be strictly prohibited any fire, and timely extinguish the test after the test is still in the Yin burning specimens. And equipped with an effective fire extinguisher device.
 
10, the use of liquefied gas, natural gas, gas and other gas sources, the pipeline interface should not leak, the vent pipe aging should be replaced in a timely manner.
 
Material combustion test under the conditions specified in Vertical Flammability Test Chamber is important to compare the relative combustion behavior of different materials, control the manufacturing process or evaluate the changes in combustion characteristics.
