| Zusammenfassung | The argon triple-point is, in most cases, the lowest temperature fixed point used in the calibration of the long-stem SPRTs in the ITS-90 (T90 = 83,805 8 K). It was also the lowest temperature point whre the calibrations of standard thermometers were compared in the frame of the CCT-K3 key comparison. Considering that a mercury fixed-point cell comparison had already taken place in the frame of EUROMET (Project No.280), and in order to provide more information for the establishment of CMCs in Europe, in the low-temperature range, it was considered as useful to organize a comparison of argon triple-point cells, and this was done in the frame of EUROMET (Project No.502). The main objective was to compare the realizations of the argon triple-point cells for long-stem thermometers and to establish the level of agreement between the results from the different participating laboratories. BNM-INM proposed to circulate one argon triple-point cell, together with the cryostat. The comparison measurements consisted of a described set of triple-point detrminations on both the circulating device and the local one. The calibration facilities were circulated with a fully described procedure to realize the fixed point and a protocol (as agreed between the different partners). This project enabled the measurement of the temperature differences between the different devices and the associated uncertainty of these differences. The paper will present the set up of the comparison, the preliminary experimental results obtained and a link between national realizations of the argon triple point as a consequence. |
