Short Description: The EN-60945 standard auto engine temperature humidity climatic combined vibration test is to investigate to what extent equipment or components are affected by the climate and dynamics factors. Compared with single factor effect, the combined environmental test can more truly reflect the adaptability of electrical and electronic products to the changes of temperature, humidity and vibration during transportation and actual use. The test can expose the defects of the product by checking their electrical properties, mechanical properties or other physical changes.
