Temperature aging test is a test method to evaluate the performance change of materials or products by placing them in a high temperature environment to simulate long-term service conditions. Common temperature aging test methods include:
Constant temperature aging test: Place the sample in a constant high temperature environment for a certain period of time, usually ranging from hours to weeks. Constant temperature aging test can evaluate the stability and durability of materials or products under high temperature conditions.
High-temperature short-term aging test: Expose the sample to a high-temperature environment, usually for a few minutes to several hours. The high-temperature short-term aging test can simulate the extreme high-temperature conditions experienced by the product in a short period of time to evaluate its rapid aging and thermal stability.
Low-temperature aging test: Expose the sample to a low-temperature environment for a certain period of time to evaluate the performance changes of materials or products under low-temperature conditions.
Alternative temperature and humidity aging test: Expose the sample to alternating high temperature, high humidity and low temperature and low humidity conditions to simulate climate changes in the real environment to evaluate the performance changes of materials or products in hot and humid environments.
The difference between these test methods lies in the difference in test temperature and duration, as well as the simulated use environment and purpose. Different test methods can be used to evaluate the performance stability, durability, thermal stability, etc. of materials or products under different temperature and humidity conditions, so as to better predict their long-term service life and reliability.
