Environmental test is a test to verify the environmental adaptability of products. After various products are manufactured , they will encounter various environments, such as high-low temperature storage environment, high-low temperature working environment, high temperature and high humidity environment, etc. For products working in these different environments, the structure and surface treatment process of the products have been adjusted and optimized to adapt to these different environments. However, for the manufactured products, whether they can work and store normally must be tested by environmental tests.
There are two types of environmental tests: simulated environmental tests and actual environmental tests. What is often used is the simulated environmental test, which is to create corresponding environmental conditions , such as high temperature and high humidity environment, high temperature environment or low temperature environment, etc., and then place the sample or test piece in this artificial environment. environment, and observe its changes after a certain period of time. Broad environmental tests also include vibration, shock, centrifugal, temperature, salt spray, high-low pressure, rays , etc. This is an environmental test concept , including outer space environments .
The actual environment test is a test in which the product is placed in a natural environment, including a test in a real use process and a test in a certain specified typical environment (such as a natural exposure test site , etc.).
