Comparison of the realisations of the ITS-90 over the range of 83.8058 K to 692.677 K

Project Description

The purpose of the comparison is to compare the results of the participating laboratories during calibration of a SPRT at fixed points in the range from the triple point of argon (-189,3442 °C) to the freezing point of zinc (419,527 °C) and at the same time to support the Calibration and Measurement Capabilities (CMC) entries of the participating laboratories. The comparison is using the same technical protocol used in the EURAMET comparison 552.­
