Environment and reliability test is an activity to ensure that the product maintains functional reliability in all environments of expected use, transportation or storage during the specified service life. The upstream of test equipment and test service industry is mainly steel, copper, iron and other metal smelting and machinery, electronics and other industries. Downstream industries are mainly divided into three categories: one is aerospace, rail transit, bridge construction, nuclear power and other industries in the field of national infrastructure; One is automobile, electronics, electrical appliances, shipbuilding and other industrial industries; There are also universities and scientific research institutes. 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.

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.

The environmental reliability test is divided into the following categories:

1、 Mechanical environment test.It mainly includes mechanical vibration, mechanical impact, drop, collision test, etc.

2、 Climatic environment test.It mainly includes temperature test, temperature and humidity test, air pressure test, salt spray test, sand dust test, water test, etc.

3、 Comprehensive environmental test。 It mainly includes temperature and air pressure comprehensive test, temperature and vibration comprehensive test, temperature and humidity vibration comprehensive test, temperature, air pressure and humidity comprehensive test, etc.

Test item name test method (common standard)

1. High temperature test (high temperature operation and high temperature storage) GB / T 2423.2-2008, IEC 60068-2-2:2007, etc

2. Low temperature test (low temperature operation and low temperature storage) GB / T 2423.2-2008, IEC 60068-2-2:2007, etc

3. High and low temperature alternating test (temperature cycle test, cold and heat shock test) GB / T 2423.2-2008, IEC 60068-2-2:2007, etc

4. High temperature and high humidity test (damp heat storage and damp heat cycle) GB / T 2423.2-2008, IEC 60068-2-2:2007, etc

5. Salt spray test (neutral salt spray, acetate spray, copper accelerated acetic acid salt spray test) GB / T 10125-2012, ISO 9227:2012, ASTM b368-2009, etc

6. UV test (xenon lamp aging / solar radiation / solar corrosion / light aging) GB / T 16422.2, ISO 4892.2, ASTM D 4459, etc

7. Drop test GB / T 2423.8-1995, IEC 60068-2-32:1990, etc

8. Waterproof test, dustproof test GB 4208-2008, IEC 60529:2013, etc

9. Vibration test (random vibration, sinusoidal vibration, vibration + temperature and humidity) GB / T 2423.10-2008, iec60068-2-6:2007, etc

10. Mechanical impact test (simulated transportation test, collision test) GB / T 2423.5, GB / T 2425.6, IEC 60068-2-27, etc
