Reliability testing is an activity undertaken to assess the functional reliability of a product over a specified life period and under all circumstances, such as intended use, transportation or storage. It is to expose the product to natural or artificial environmental conditions to be subjected to its action, so as to evaluate the performance of the product in the actual use, transportation and storage of environmental conditions, and analyze and study the degree of influence of environmental factors and their mechanism of action. Through the use of a variety of environmental test equipment to simulate the climate environment of high temperature, low temperature, high temperature and high humidity and temperature changes, accelerate the reaction of the product in the use of the environment, to verify whether it has reached the expected quality objectives in the research and development, design, manufacturing, so as to evaluate the product as a whole, to determine the product reliability life.
