In today's increasingly fierce competition, the function and appearance of products are no longer the focus of competition between brand enterprises, and the quality and reliability of products are increasingly valued by the market and customers. The purpose of PTTS reliability testing is to ensure that the product during the specified life period, under the expected use, transportation or storage environment, the activity of maintaining its function. The influence degree and mechanism of environmental factors are analyzed and studied. Through the use of various environmental test equipment to simulate the high temperature, low temperature, high temperature and high humidity and temperature changes in the climate environment, accelerate the possible failure of the product in the use environment to verify whether it meets the expected quality objectives in research and development, design and manufacturing, so as to evaluate the product as a whole to determine the product reliability life.
PTTS evaluation and analysis of product reliability are divided into the following three categories:
