The low-g shock standard device based on rigid body collision for shock acceleration calibration was investigated and established, with the half-sine squared acceleration shape range from 20m/s2 to 10000 m/s2 and pulse duration from 0.5 ms to 10 ms. The expanded calibration uncertainty of sensitivity of shock accelerometers by laser interferometry is 1%, k=2. The structure of the device and key technology involved were described．The pulse generation materials were explained．The calibration results and uncertainty evaluation were provided．This low-g shock standard device is used for piloting international shock comparison APMP.AUV.V-P1.
