The results of experimental comparisons of the COOMET 706/RU-A/16 national standards of the unit of propagation velocity of longitudinal ultrasonic waves in solids are presented. The comparisons were performed in 2018–2021 with the participation of national metrological institutes of Russia, Belarus, Ukraine and China. The primary objective of these comparisons was verification of the measurement capabilities of the participating laboratories, analysis of the components of measurement uncertainty, and evaluation of the reproducibility of the measurement results, as well as a test of the traveling transfer standards, and the schedules and methods of their transportation. For the first time in the metrology of acoustic measurements in solids, comparisons of six national standards were carried out, which implemented various methods of excitation and registration of ultrasound (non-contact optical and capacitive methods, immersion piezoelectric method) and various methods of measurement of the propagation velocity of longitudinal ultrasonic waves in solids (pulse echo, resonance, through-transmission substitution technique). Taking account of the stability of the characteristics of the traveling transfer standards of comparison, a hybrid comparison scheme was used. Samples (velocity measures), made of quartz glass, BK8 optical glass, and 40Kh13 steel were used as references of comparison The measurements of the propagation velocity of longitudinal US waves in samples were performed at the frequencies 2.25–2.5, 5, and 10 MHz in accordance with the measurement procedure adopted on this standard. The comparisons showed the consistency of most of the measurement results obtained in the participating laboratories. Individual discrepancies in the results of the comparisons may be related to the possible underestimation of the quoted standard uncertainties of measurements by the participants in the comparisons, as well as the presence of unaccounted for influencing factors, which requires additional study to determine the causes.
