This part of ISO 16063 specifies the instrumentation and procedure to be used for primary shock calibration of rectilinear accelerometers, using laser interferometry to sense the time-dependent displacement during the shock. The method is applicable in a shock pulse duration range 0,05 ms to 10 ms and a range of peak values of 102 m/s2 to 105 m/s2 (pulse-duration dependent). The method allows the shock sensitivity to be obtained.
