Euramet.T-S3: Results and calculation of comparison reference value
Original language description
In order to support the Calibration Measurement Capabilities (CMC) for the calibration of thermocouples up to 1492 ºC of some laboratories, a comparison of the calibration of Pt/Pd thermocouples was carried out within EURAMET: the supplementary comparison EURAMET.T-S3. The comparison was organized in three loops with nineteen participating laboratories and it allowed the performance of the measurement either in fixed points and/or by comparison. The method used to analyse the results of the comparison was the generalized weighted mean that takes into account the full covariance matrix that includes correlations between the participants which have similar traceability sources and between measurements performed by the same laboratory (i.e. the pilots that performed measurements at the beginning and at the end of each loop and the measurements performed by the same laboratory in fixed points and by comparison at the same calibration point). This paper will present a summary of the results obtained in the comparison and the detailed process of the data treatment to calculate the comparison reference value. Furthermore, different alternatives for the comparison reference value will be analysed and compared with the probability distribution, obtained numerically by combining the individual laboratory distributions using Monte Carlo techniques.
