Shock waveforms were investigated by considering the frequency response of undamped acceleration transducers in primary vibration calibration. For the purpose, the sensitivity and phase delay from 100 Hz to 5 kHz were calibrated in compliance with ISO 16063-11. Then, three shock waveforms with different pulse width and a peak acceleration 1000 m/s2 were evaluated to check the effect of the shock waveforms by the relative frequency response. As the results, the shorter the shock was, the higher the peak acceleration increased. Also, the linearity was evaluated in shock calibration from 1000 m/s2 to 5000 m/s2, and the sensitivity dependence on acceleration level was constant.
