How to use the needle flame combustion test machine?

Needle flame combustion test machine is a kind of equipment used to test the combustion performance of materials. The following are the steps to use the needle flame combustion test machine: 1.Prepare test samples: cut the material to be tested into samples of the specified size, and ensure that the surface of the sample is flat and clean. 2. Adjust the test parameters: according to the standard requirements, set the flame height, combustion time and other parameters of the needle flame combustion test machine. 3. Test: Put the sample on the test stand, turn on the burner, and apply the flame. Within the specified time, observe whether the sample is ignited and whether the pheroblysis product is produced. 4. Record the experimental results: observe the combustion of the sample and record whether molten droplets occur, combustion speed, combustion time and other data. 5. Analysis and evaluation: According to the experimental results, the combustion performance of the sample is evaluated in combination with relevant standard requirements. It should be noted that when using the needle flame combustion test machine, the relevant safety operating procedures should be followed, such as ensuring good indoor ventilation and avoiding the accumulation of flammable gases.At the same time, the experimental operation should be carried out by professionally trained personnel.
