Description

[0002] In the actual use of various products, the products must face certain environmental conditions, including centrifugal and climate factors, which will produce corresponding environmental stress on the products. The effects of centrifugal and climate include not only the effects caused by them alone, but also the combined effects caused by the mutual influence of centrifugal, climate and environment, which is not conducive to the actual use of the products. In order to ensure the performance of the products in actual use, centrifugal and climate (i.e. temperature and humidity) tests should be carried out on the products before they leave the factory to simulate the real working environment of the products to the greatest extent and test the performance of the products in this environment.
