Drop Calibration of Accelerometers for Shock Measurement

Abstract

This report details the Drop Calibration Method for determining the sensitivity of shock accelerometers. The Drop Calibration Method requires the accelerometer under calibration and either a traceable acceleration standard or a traceable force transducer standard to undergo a series of drop impacts. The sensitivity of the accelerometer is determined by comparing the outputs of the accelerometer and the standard. By appropriate characterisation of both the accelerometer's and the standard's data channels, prior to the calibration drops, the Drop Calibration Method ensures that the resultant sensitivity is traceable to National Association of Testing Authorities, Australia (NATA) standards.
