GB/T 2423.11-1997 Environmental testing for electric and electronic products. Part 2: Test methods. Test Fd: Random vibration wide band--General requirements (English Version)
Random vibration testing is complex, so the standard is quite extensive. Therefore, this standard gives in this introduction the layout of the test method and the rationale on which it is based. It must be noted that throughout the text of the standard two terms of particular importance in random vibration testing problems are frequently referred to. In order to enable readers to better understand the content of this standard, it is defined as follows: Acceleration spectral density acceleration spectral density (ASD) The spectral density of acceleration variables, expressed as the square of the acceleration unit per unit frequency. Spectrum of the acceleration spectral density ASD spectrum How the acceleration spectral density varies in the frequency range.
