[0002] Environmental reliability testing is a key means of evaluating whether a product can maintain its functional reliability during its entire life cycle under various environmental conditions such as use, transportation or storage. Through environmental testing, various complex actual working conditions can be simulated to verify the impact of environmental factors on product performance and analyze their mechanism of action. This type of test is widely used in many fields such as automobiles, communications, and electronic appliances to help companies improve product reliability and market competitiveness.
