GB/T 2423.56-2023 "Environmental Testing - Part 2: Test Methods - Test Fh: Broadband Random Vibration and Guidance" is applicable to products that may be subjected to random vibration during transportation or operation. It specifies the test methods and requirements for broadband random vibration. The standard defines core parameters such as the test frequency range, acceleration root mean square (RMS) value, and crest factor, with the crest factor required to be ≥2.5. For non-Gaussian tests, kurtosis and skewness must also be recorded. The test employs single-point or multi-point control methods, with a reference point tolerance of ±3 dB. Dynamic loads are simulated using equipment such as vibration test systems and control instruments to evaluate the sample's ability to withstand stress accumulation and functional degradation.
