A Round Robin Test of Piezoresistive Shock Accelerometers between Shock and Centrifuge Calibrations

Abstract

A round robin test of piezoresistive accelerometers was carried out to confirm a consistency between shock and centrifuge calibrations among five participants; AIST, KYOWA, TTDC, JARI and NICS. AIST evaluated the accelerometers using shock calibration system in compliance with ISO 16063-13, and the shock calibration included various frequency components. On the other hand, the others evaluated them using centrifuge calibration system in compliance with ISO 5347-7, and the centrifuge calibration based on DC (direct current) measurement. Finally, the shock and centrifuge calibrations were implemented from 1000 m/s² to 5000 m/s², and the consistency using Z scores with the standard deviation of 0.9 % was satisfied among five participants.
