The analysis and selection of the methodology for processing the results of interlaboratory comparisons (IC) were carried out. The universal algorithm for processing the primary IC data was proposed, which allows the reference laboratory to take into account all the features of reporting on ICs. The transmission sample for IC on the calibration of time meters was investigated. The reference values and corresponding expanded uncertainties for this IC are determined. The results of interlaboratory comparisons of calibration results of the time meter at points from 30 s to 3600 s are presented. Comparison of the results obtained during the calibration of the time meter by ten laboratories was carried out according to the radial scheme within 2016. The deviations of the results obtained by each laboratory were determined and the correctness of the results was evaluated taking into account the measurement uncertainty using the criterion for the performance statistics for the selected time intervals. The competence of the staff of laboratories participating in IC on the calibration of time meters was estimated. An analysis of the evaluation results showed that the staff of eight out of ten laboratories, including the reference one, has a high level of competence. It has been established that, unlike other factors, the competence of the staff of laboratories participating in IC has little effect on the IC results.
