Mechanical vibration and shock -- Signal processing -- Part 4: Shock-response spectrum analysis
This standard was last reviewed and confirmed* in 2015.
*Therefore this version remains current
ISO 18431-4:2006 specifies methods for the digital calculation of a shock-response spectrum (SRS) given an acceleration input, by means of digital filters. The filter coefficients for different types of shock-response spectra are given together with recommendations for adequate sampling frequency.
