説明

Shock acceleration measurement is widely carried out in a variety of applications such as air-bag control of automobiles or drop testing of mobile instruments, in which accelerometers are a key device to evaluate human safety or product reliability. However, despite the fact that accelerometers have the non-linear sensitivity in relation to frequency and acceleration level, many Japanese private laboratories calibrate accelerometers by the means of comparison calibration in which each reference is traceable to different oversea national standards. Since it is difficult for comparison calibration to evaluate the non-linear characteristic, we developed the shock acceleration calibration system with Japanese time and length standards for primary calibration. In order to enhance the reliability of shock acceleration measurement, it is essential to confirm the equivalence of accelerometer's calibration results between primary and comparison calibrations. So, a round robin test was executed among the National Institute of Advanced Industrial Science and Technology (AIST) and the three Japanese private laboratories. The calibration results among the four laboratories were matched within a difference of 0.17% and En value of 0.58. Also, the non-linear characteristic did not affect the calibration results on the experimental condition of this round robin test.
