Abstract

The results of the SIM key comparison in the primary vibration calibration of the complex charge sensitivity (magnitude and phase shift) concerning steady-state sinusoidal vibration are presented. This regional key comparison followed the global CCAUV.V-K5 comparison over the extended frequency range from 10 Hz to 20 kHz. Measurement results reported by the two participants for magnitude and phase shift of complex charge sensitivity of back-to-back and single ended accelerometers were compared. A link to the CCAUV.V-K5 with the respective Degrees of Equivalence are reported.

Note that this text is that which appears in Appendix B of the BIPM key comparison database https://www.bipm.org/kcdb/.

The final report has been peer-reviewed and approved for publication by the CCAUV, according to the provisions of the CIPM Mutual Recognition Arrangement (CIPM MRA).
