The technical report summarizes the results provided by the Resistance laboratory of the National Research Institute (INRIM) concerning the calibration of two 1 Ω and two 10 kΩ standard travelling resistors related to the comparison BIPM.EM-K13.a (1 Ω resistance standards) and BIPM.EM-K13.b (10000 Ω resistance standards) which constitute the BIPM programme of on-going bilateral comparisons of resistance standards. The chosen resistors normally assure a transfer uncertainty less than a few parts in 108. The comparison was carried out following an initial/return measurement pattern: the BIPM travelling standards were first calibrated at the BIPM then they were sent to INRIM where they were calibrated, and finally re-calibrated after their return at the BIPM. All measurement results will be corrected to the reference temperature (23.000 °C) and the reference pressure (1013.25 hPa). The result of the comparison will be expressed as the difference between the calibrations from the two laboratories, together with its associated uncertainty. The pilot laboratory was the BIPM.

Abstract

The technical report summarizes the results provided by the Resistance laboratory of the National Research Institute (INRIM) concerning the calibration of two 1 Ω and two 10 kΩ standard travelling resistors related to the comparison BIPM.EM-K13.a (1 Ω resistance standards) and BIPM.EM-K13.b (10000 Ω resistance standards) which constitute the BIPM programme of on-going bilateral comparisons of resistance standards. The chosen resistors normally assure a transfer uncertainty less than a few parts in 108. The comparison was carried out following an initial/return measurement pattern: the BIPM travelling standards were first calibrated at the BIPM then they were sent to INRIM where they were calibrated, and finally re-calibrated after their return at the BIPM. All measurement results will be corrected to the reference temperature (23.000 °C) and the reference pressure (1013.25 hPa). The result of the comparison will be expressed as the difference between the calibrations from the two laboratories, together with its associated uncertainty. The pilot laboratory was the BIPM.
