Bilateral comparison between LNE-Cnam and KIM-LIPI to:
1) demonstrate KIM-LIPI's technical capabilities
2) link KIM-LIPI to main regional comparison EUROMET.T-K4
Final Report 2016-05-02
The thermometer RS90Z-7 of METROLOGI-LIPI has been measured at the freezing points of silver and aluminum at LNE-Cnam. At the silver freezing point, it shows a severe instability. At the aluminum freezing point it is reproducible within 1 mK, but shows a large deviation.
Such values do not allow assessing the calibration uncertainties declared by METROLOGI-LIPI at the freezing point of silver and aluminum.
It was not possible to solve the instabillity problems. So the comparison was stopped.
