Show affiliationsAs a part of the ongoing BIPM key comparison BIPM.EM-K11.a and b, a comparison of the 1.018 V and 10 V voltage reference standards of the BIPM and the Instituto Nacional de Tecnologia Industrial (INTI), Buenos Aires, Argentina, was carried out from August to October 2009.
The final result of the comparison is presented as the difference between the value assigned to DC voltage standard by INTI, at the level of 1.018 V and 10 V, at INTI, UINTI, and that assigned by the BIPM, at the BIPM, UBIPM, at the reference date of the 17th of September 2009:
UINTI − UBIPM = − 0.01 μV; uc = 0.03 μV, at 1.018 V
UINTI − UBIPM = − 0.24 μV; uc = 0.38 μV, at 10 V
where uc is the combined standard uncertainty associated with the measured difference, including the uncertainty of the representation of the volt at the BIPM and at INTI, based on KJ-90, and the uncertainty related to the comparison.
