Although the reliability test and the environmental test are closely related, they have distinct differences in the purpose of the test, the amount of environmental stress used, the selection criteria of the environmental force value, the type of test, the test time, and the test termination criteria. The following article will be explained in the small series for everyone. First, the purpose of the test Environmental testing is a test that targets the suitability of the product for the intended working environment, including the ability to withstand the toughest storage and transportation environments without damage and functioning properly under reasonable environmental conditions. The reliability test is a test designed and carried out according to the reliability requirements, with reliability targets and under typical environmental conditions. It is a test to verify whether the product can achieve the predetermined function under the specified conditions and within the specified time. It is reliable. General term for sexual growth test, reliability development test and reliability verification test. Second, the difference in the amount of environmental stress used For environmental testing, 19 test items are specified in GJB 150, 20 environmental test items are specified in MIL-STD-810 D, and 810F is added to 24 test items, including environmental stresses that are more important to the product, such as : temperature, humidity, salt spray, vibration shock, pressure, solar radiation, sand dust, rain and so on. The test product should be selected according to its future environmental conditions and the degree of impact. Generally, more than 10 environmental stresses should be investigated. The reliability test, based on comprehensive simulation, only combines the combined environmental stress (temperature, humidity, vibration) with electrical stress. It can be seen that the number of environmental stresses selected for the reliability test is much less than the environmental test.
