GB/T 2423.56-2023 "environmental testing Part 2: Test methods, Test Fh: Broadband random vibration and guidelines" is one of the important parts of the Chinese national standard on environmental testing. The standard stipulates that under laboratory conditions, by applying broadband random vibration to evaluate the vibration environment that equipment, products or materials may be subjected to during transportation or use. Test Fh is designed to simulate the various vibration conditions that equipment is subjected to in actual use to evaluate its tolerance and performance Stability in a vibration environment. This standard describes in detail the test implementation method, including the requirements of the vibration system, the setting of test parameters, and the data recording and analysis methods, providing technical guidance and basis for evaluating the Reliability of products in a vibration environment.
