GB/T 2423.56-2018 "Environmental testing Part 2: Test methods, Test Fh: Broadband random vibration and Guidelines" standard specifies the basic requirements and methods of broadband random vibration test. The standard describes in detail how to conduct broadband random vibration test in environmental test to simulate the complex vibration environment of equipment in actual use. Including the selection of test equipment, test setting, implementation steps and result analysis. Broadband random vibration test is mainly used to evaluate the vibration resistance performance of equipment over a wide Frequency range to ensure that it has sufficient Reliability and Stability in practical applications.
