This paper presents the chain of calibration for acoustics and vibration measurement instruments to national standard which must be maintained by NMI (National Metrology Institute). At the present time, NMI in Indonesia is Research Center for Metrology - Indonesian Institute of Sciences (RCM-LIPI). For acoustics measurement instruments are microphone, pistonphone and sound level meter, and for vibration measurement instruments are accelerometer and vibration meter. The implementation of calibration method based on IEC standard is described along with the uncertainty components that contribute to the calibration results. International recognition of calibration and measurement capabilities of RCM-LIPI for acoustics and vibration are shown.
