Abstract
This report describes the results obtained in a bilateral comparison of primary vibration calibration facilities. Two piezoelectric standard accelerometers (one single-ended as well one back-to-back type) were calibrated first at METAS, then at the PTB and again at METAS after their return.The METAS and the PTB calibrations were found to be in excellent agreement, with a mean difference smaller than the expanded uncertainty (k = 2) of the comparison.Main text.To reach the main text of this paper, click on Final Report. Note that this text is that which appears in Appendix B of the BIPM key comparison database kcdb.bipm.org/.The final report has been peer-reviewed and approved for publication by the CCAUV, according to the provisions of the CIPM Mutual Recognition Arrangement (MRA).
