Parameters

Test Procedures

Sample Preparation: Prepare cubic samples of the insulation material with dimensions of (100 × 100 × 100) mm³. If the material thickness is less than 100 mm, use a stacking method for preparation, ensuring that the temperature-measuring thermocouple is not located at a joint.

Equipment Preheating: Start the test furnace and adjust the heating power to stabilize the average furnace temperature at (750 ± 5) °C for at least 10 minutes. During this period, the temperature drift should not exceed 2 °C, and the maximum deviation from the average temperature should not exceed 10 °C.

Sample Installation: Place the sample in the sample holder, ensuring the central thermocouple is accurately positioned. Then, quickly (within 5 seconds) suspend the sample holder in the designated position inside the furnace.

Test Start: Close the furnace door, start the timer, and record the temperature measured by the thermocouple inside the furnace.  Simultaneously monitor the surface and center temperatures of the sample (if required).

Test Monitoring: Continuously observe the sample's condition, recording temperature changes and any abnormal phenomena during the test.

Test Termination: The test duration is 24 hours, or the test can be terminated early when the furnace temperature reaches final equilibrium (temperature drift not exceeding 2 °C within 10 minutes). If equilibrium is not reached after 60 minutes, the test should also be terminated.

Result Judgment: Within the 24-hour test period, if the sample's center temperature does not exceed 600 °C, it is judged as qualified; if it exceeds 600 °C, it is judged as unqualified.

Equipment Cleaning: After the test, remove the sample holder, clean any residue from the furnace, and turn off the equipment power.
