Pre-preparation: Before conducting the cone calorimeter test, it is necessary to ensure that the instrument is in normal condition. Carefully check whether the connection of each component of the instrument is stable and the power supply is stable. At the same time, prepare the samples to be tested to ensure that the samples are uniform and meet the test specifications. It is also necessary to calibrate the instrument in advance to ensure the accuracy of the test data.

Sample placement: Precisely place the processed sample into the sample compartment of the cone calorimeter. Pay attention to the accurate placement position to avoid contact between the sample and the inner wall of the instrument and prevent affecting the test results. After placement is completed, close the sample compartment to ensure good sealing of the instrument and create a stable environment for subsequent testing.

Parameter setting: According to the test requirements and sample characteristics, set the test parameters reasonably on the instrument operation interface, such as temperature range, heating rate, etc. Different samples have different requirements for test parameters. Accurate setting of parameters is the key to obtaining reliable data. Check carefully after setting to ensure that it is correct.

Start the test: After confirming that the parameters are set correctly, start the cone calorimeter. The instrument will operate according to the setting procedure, monitor and record the heat change data of the sample during the test in real time. During the test, pay close attention to the running status of the instrument, and suspend the investigation in time if there is any abnormality.

Data reading and analysis: After the test, derive the test data from the instrument. Organize and analyze the data, and calculate the heat-related indicators of the sample according to relevant standards and formulas. If there is any deviation in the data, check the links in the test process and re-test if necessary to ensure the accuracy and reliability of the results.
