Bilateral Comparison EURAMET. AUV.V-K1.2 (vibration acceleration)

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.
