Temperature, humidity and vibration three comprehensive test

 

Introduction to the three comprehensive tests

 

The three comprehensive tests refer to tests that combine three environmental stresses of temperature, humidity and vibration. This test is used to assess the adaptability of the product in transportation and use under the combined environment of temperature, humidity and vibration. Compared with the single factor, it can more accurately reflect the adaptability of electrical and electronic products to changes in temperature, humidity and vibration composite environment during transportation and actual use. The defects of exposed products are new product development, prototype test and product qualification. An important test method essential to the whole process of the test.
