Environmental reliability test refers to the ability of products to complete specified functions under specified conditions and within specified time. In the process of design and application, the product is constantly affected by its own and external climatic environment and mechanical environment, but still needs to be able to work normally, so it needs to be verified with test equipment. For related products, environmental reliability test is very necessary.

According to the national standard gb-6583, environmental reliability refers to the ability of a product to complete the specified functions under the specified conditions and within the specified time. In the process of design and application, the product is constantly affected by its own and external climate environment and mechanical environment, but still needs to be able to work normally, so it needs to be verified with test equipment. This verification is basically divided into three parts: R & D test, trial production test and mass production sampling inspection. Reliability includes durability, maintainability and design reliability.

Generally, environmental reliability test is divided into the following three categories: mechanical environmental test, climatic environmental test and comprehensive environmental test. Mechanical environment test mainly includes mechanical vibration, mechanical shock, drop, collision, steady-state acceleration test, etc.; climate environment test mainly includes temperature test, temperature and humidity test, air pressure test, water test, salt spray test, sand dust test, gas corrosion test, etc.; comprehensive environment test mainly includes temperature and pressure comprehensive test, temperature vibration comprehensive test, temperature and humidity vibration comprehensive test Comprehensive test of temperature, air pressure and humidity, etc.
