Thermal performance testing must follow standardized procedures to ensure consistent results.
Typical methods include: sample preparation, where samples are cut or shaped according to standard requirements, ensuring a smooth and contaminated surface; instrument calibration, using standard materials to calibrate the equipment for temperature and energy; test execution, selecting appropriate procedures based on the project, such as thermogravimetric analysis scanning the sample at a constant heating rate, differential scanning calorimetry recording heat flow curves under an inert atmosphere, and laser scintillation calculating thermal conductivity parameters through transient measurements; data recording and analysis, where software automatically processes raw data, generates thermal curves, and extracts characteristic values; and repeatability verification, confirming that the result deviation is within acceptable limits through multiple tests. The entire process requires strict control of environmental conditions, such as humidity and air pressure, to avoid external interference.
