The global metrological traceability fully depends on the implementation of international mutual recognition agreements in field of metrology. The linked results of international comparisons of national standards for alternating current/direct current (AC/DC) voltage transfer difference measurements and electrical power measurements, and national inter-laboratory comparison AC/DC voltage transfer difference and electrical power measurements at industrial frequency was presented. The main goal of this inter-laboratory comparison was the assessment of calibration laboratories capabilities that perform calibration in AC/DC voltage transfer difference and electrical power measurements. The consistency of the data obtained using the En numbers and Chi² test was estimated.
