What is environmental reliability testing? Environmental reliability refers to the ability of a product to complete specified functions within specified time under specified conditions. In the process of design and application, the product is constantly affected by its own and external climatic environment and mechanical environment. It needs to be able to work normally and needs to be verified with test equipment. It covers the application fields of electronics, automobile, rail transit, universe, ships, household appliances, information technology equipment, photovoltaic and so on.

Generally, the environmental reliability test is divided into three types: mechanical environmental test, climatic environmental test and comprehensive environmental test.

Mechanical environment test mainly includes mechanical vibration, mechanical impact, falling, collision, stable acceleration test, etc.; climatic environment test mainly includes temperature test, temperature and humidity test, air pressure test, water test, salt spray test, dust test, gas corrosion test, etc.; comprehensive environment test mainly includes temperature and pressure test, temperature vibration test, temperature and humidity vibration test, temperature, pressure and humidity test, etc.

Environmental reliability test can verify product reliability in product development stage, trial production stage and batch production inspection stage, which helps enterprises save R & D and production costs and improve product quality.

Environmental reliability generally includes climatic environmental reliability and mechanical environmental reliability.

1. the influence of climate and environment reliability includes the influence of temperature, humidity, light, rain, salt fog, air pressure, etc. The climatic environment reliability test items mainly include: high temperature test, low temperature test, rapid temperature change test, cold and heat shock test, constant damp heat test, alternating damp heat test, combined cycle test of temperature and humidity, light aging test, waterproof test, dustproof test, salt spray test, low pressure test, etc.

2. the mechanical environment reliability test items mainly include: vibration test, mechanical impact test, collision test and drop test.

3. in addition, it includes comprehensive environmental reliability test: comprehensive environmental test, such as the test combining temperature + humidity + vibration.
