GB/T 2423.13-1997 Environmental testing for electric and electronic products. Part 2: Test methods. Test Fdb: Random vibration wide band--Reproducibility medium
Determines the ability of components and equipment to withstand random vibrations at specified levels of severity. This random vibration test is applicable to components and equipment that may be affected by random vibration conditions during use. The purpose of the test is to determine mechanical weakness and/or degradation of specified performance and to use this information in conjunction with the relevant specification to decide whether the test sample is acceptable. The test sample is subjected to a random vibration test of a given level over a wide frequency range while applying the environmental stress specified in this test (conditional test). Due to the complex response of the test specimen and its fixtures, this test requires special attention to the preparation, conduct, and verification of its specified requirements.
