Constant temperature and humidity test

The constant temperature and humidity test is also called the constant humidity and heat test. The purpose is to understand the performance changes of the product under the set constant temperature and humidity conditions. The purpose is to discover various defects in the product's design, materials and processes as early as possible. After analysis and improvement, the product reliability will gradually increase and eventually reach the predetermined design level; to provide information to improve the product's combat readiness integrity, increase mission success rate, and reduce maintenance and support costs; to confirm whether it meets the quantitative requirements under the specified temperature and humidity conditions.
Constant temperature and humidity tests are mainly used for equipment testing the performance of materials in various environments and testing the heat resistance, cold resistance, dryness resistance, and moisture resistance of various materials.
