The test to measure, verify or improve the reliability of products is called reliability test. It is an important link of product reliability. The quality inspection refers to whether the characteristics of the product are consistent with the specified standards, mainly considering the compliance. The reliability test is generally phased, while the quality inspection is routine.

There are many classification methods for reliability test:

1. If divided by environmental conditions, it can be divided into simulation test and field test under various stress conditions;

2. Divided by test items, it can be divided into environmental test, life test, accelerated test and various special tests;

3. If it is divided according to the purpose of the test, it can be divided into screening test, identification test and acceptance test;

4. If divided according to the nature of the test, it can also be divided into destructive test and non-destructive test.

5. However, the commonly used classification method is to classify it into five categories: A. environmental test B. life test C. screening test D. field use test E. identification test 1 Environmental test is to assess the adaptability of products under various environmental conditions (vibration, impact, centrifugation, temperature, thermal shock, hot tide, salt spray, low pressure, etc.), and it is one of the important test methods to evaluate the reliability of products.

Application of reliability test:

Computers: computers, monitors, mainframe, computer components, medical equipment and other precision instruments

Electronic communication: mobile phones, RF devices, routers, electronic communication components, etc

Electrical appliances: household appliances, lamps, transformers and other electrical equipment

Others: packing boxes, transportation equipment, outdoor materials, etc

Reliability test items:

1. Temperature and humidity aging test, constant temperature and humidity test, high and low temperature alternating damp heat test, high temperature aging test, rapid temperature change test, walk-in high and low temperature damp heat laboratory, cold and heat shock test, high, low temperature and low pressure test.

2. Physical and mechanical property test, electric vibration test, three comprehensive tests (temperature, humidity and vibration), electronic universal testing machine (tension and pressure), tensile test (including normal temperature and high and low temperature), impact test (including normal temperature and high and low temperature), simulated automobile transportation vibration test and drop test.

3. Weathering aging test, xenon arc lamp aging test, carbon arc lamp aging test, simulated ultraviolet aging test, natural exposure aging test and ozone aging test.

4. Salt spray corrosion test, neutral salt spray test, acetate spray test, copper ion accelerated salt spray test, temperature cycling salt spray test.

5. Other project tests, rain test, enclosure protection level test (IP code), sand dust test, water pressure test, noise test, vertical combustion test and horizontal combustion test.
