VERIFICAREA CORECTITUDINII M?SUR?RILOR EFECTUATE ?NLABORATOARELE DE METROLOGIE

摘要

This paper presents the manner to demonstrate the competence of the metrological laboratoriesrninvolved in the dissemination of the DC voltage unit. The measurements were made for the values ofrn1,018 V and 10 V. It was calculated the standard deviation for the measured voltages of eachrnlaboratory related to the reference voltage and were determined the values of the indexes for thesernlaboratories. It was estimated the uncertainty for the standard deviation. In the paper are shown thernresults of the measurements for each of the six laboratories that were participated and for thernreference laboratory. As itinerant standard was used an electronic DC voltage calibrator with therncapability to generate two output voltages: 1,018 V and respectively 10 V. The result of the analysis ofrnthe results that were sent by these laboratories demonstrate that all laboratories were inside of thernacceptance limits for the value of the index. Thus, all the laboratories are capable to transmitrncorrectly the DC voltage unit, inside of the uncertainty assumed by each laboratory. All thernmeasurements made by the participant laboratories are compatible.
