The comparative analysis of the results of the RMO international supplementary comparison of national standards of the units of inductance is conducted with the aim of evaluation of convergence. For the comparison, the reference values with the expanded uncertainties are calculated and the degrees of equivalence of standards of participants and expanded uncertainties for the nominal values of measures of 10 mH and 100 mH on a frequency of 1 kHz are determined. Metrological traceability of the national standard of every participant of comparisons to the units of the International system of units SI is determined. For verification of consistency of the results of comparisons, the values of the χ2 criterion for the results of comparisons of standards of participants taking into account the measurement uncertainty are calculated. The obtained values of the criterion of consistency for the participants can be considered consistent, which is the objective confirmation of the measurement uncertainties declared by the participants.The evaluation of calibration and measurement capabilities of Ukraine for the unit of inductance is realized. The methodology of evaluation of measurement uncertainty in a wide range of inductance values (from 10 µH to 100 H) is proposed. The results of the calculations of the values of measurement uncertainties according to the proposed methodology revealed that the results correspond to the data published in the international key comparison database for Ukraine in the range of capacitance values from 10 µH to 10 H on a frequency of 1 kHz Author Biographies Oleh Velychko, State Enterprise “All-Ukrainian State Scientific and Production Centre for Standardization, Metrology, Certification and Protection of Consumer” (SE “Ukrmetrteststandard”) Metrolohychna str., 4, Kyiv, Ukraine, 03143 Doctor of Technical Sciences, Professor, Director Scientific and Production Institute of Electromagnetic Measurements
