Special requirements for the qualification of safety-related equipment are presented. The importance of the simultaneous application of all concurrent loads (e.g., vibratory motion, temperature, pressure, nozzle loads) is explained. In addition, reasons are given for the simultaneous application of the three components of the vibratory motion. Attention is drawn to the need for the test response spectra closely enveloping the required response spectra. The input motion should not have frequency contents higher than the frequency at the onset of the rigid response in the required response spectra.
