Reliability test is an activity to evaluate the functional reliability of products in all environments such as expected use, transportation or storage within the specified service life. It refers to exposing the product to natural or artificial environmental conditions to withstand its effects, so as to evaluate the performance of the product under the environmental conditions of actual use, transportation and storage, and to analyze and study the impact degree and mechanism of environmental factors. By using various environmental test equipment to simulate the high temperature, low temperature, high temperature, high humidity and temperature changes in the climate environment, accelerate the reaction of the product in the use environment to verify whether it meets the expected quality objectives in the research, development, design and manufacturing, thus evaluating the overall product to determine the product reliability life.
