Abstract As pilot lab, National Institute of Metrology, organized Asia Pacific Metrology Programme pilot comparison of primary low-g shock acceleration calibration from August, 2013 to December, 2014. The comparison covers primary shock calibration systems using laser interferometry with two basic types of low-g shock exciters from 4 participating labs. The peak value of shock acceleration for comparison of monopole shock pulse is from 500m/s2 to 5000m/s2 with pulse duration from 0.5ms to 5ms, and for comparison of dipole shock pulse is 1000m/s2 with pulse duration from 0.03ms to 0.2ms. The comparison results show that the deviations of participants’ measurement results from reference values are within the associated uncertainties.
