　　Today, the article I want to share with you is how to test the car rearview mirror in the high and low temperature test chamber? Before answering this question, let us first understand the car rearview mirror. In the process of car driving, the rearview mirror is particularly important. Without a rearview mirror, the driver will not be able to see the information behind, to the side, and below, which is particularly dangerous. The quality of the rearview mirror, as a very important part of the car, needs to be strictly controlled. Will it burst in the hot summer? Will it crack directly in a low temperature environment? In order to ensure quality, manufacturers will conduct reliability tests before the product leaves the factory. Today, I will take the high and low temperature test chamber as an example. Let's talk about the test methods of car rearview mirrors!

　　① After the high temperature working test is performed at 60℃±2℃ for 8 hours continuously, the test equipment can work normally and the functions can work normally, etc. The test result is "qualified";
