KEY COMPARISON

This report describes the results obtained from a CMI–BIPM bilateral comparison of 10 kΩ resistance standards in 2008. The comparison was carried out in the framework of the BIPM ongoing key comparison BIPM.EM-K13.b. Two BIPM 10 kΩ travelling standards of SR104 type were calibrated first at the BIPM, then at the CMI and again at the BIPM after their return. The stability of the transfer standards was such that the uncertainty associated with the transfer was significantly smaller than the uncertainty arising from the calibrations. The CMI and the BIPM calibrations were found to be in good agreement, with a mean difference smaller than the standard uncertainty of the comparison.
