Environmental test:

Environmental testing is the exposure of products to the natural environment or artificially simulated environments to evaluate the performance of the products under conditions of storage, transport, and use that they actually encounter. Environmental testing can provide information on design quality and product quality and is an important means of quality assurance.

Reliability test:

Reliability test refers to the ability of a product to perform a specified function within a specified period of time under specified conditions. In the process of design and application, products are constantly subjected to their own and external environmental impacts and mechanical environment, but they still need to be able to work normally. This needs to be verified by test equipment. This verification is basically divided into R&D and trial production tests. , mass production sampling three parts.
