This standard is specifically designed to evaluate the aging resistance of vulcanized rubber in humid and high-temperature air environments. The core principle involves placing test specimens in a controllable temperature and humidity thermal aging test chamber to simulate long-term usage conditions. After a specified period, the specimens are removed, and the changes in key mechanical properties (such as tensile strength, elongation at break, hardness, etc.) before and after aging are compared to assess the rubber's resistance to thermal and humid aging. This method provides an important technical basis for predicting the service life and reliability of rubber products under hot and humid conditions.
