| Zusammenfassung | A bilateral comparison of primary standards for sound in air, COOMET.AUV.A-K1.1 was conducted in 2004 between the DNDI (Ukraine) and the PTB (Germany) with PTB acting as the linking laboratory to the previous COOMET.AUV.A-K1 comparison. A similar protocol was followed, and although measurements were made at 23 acoustic frequencies, the results were analysed in terms of degrees of equivalence only at the recommended frequencies of the CCAUV.A-K1 comparison so that the appropriate links could be made. The results were approved by CCAUV in October 2008 are in agreement with all the linked results within the uncertainties. |
