- Abstract:
- The present paper discusses an example of application of a method for the comparison of calibration curves. The method, presently in development, is expected to be an useful tool for the analysis of complex sets of data in several situations; two possible examples are the analysis of the drift of instrument with complex calibration curves or the analysis of data in Key Comparisons performed for quantities which require the use of measurement instruments as Transfer Standards.
The proposed example is based on data from a Key Comparison.
The paper discusses the merits of both the technique proposed for the determination of a reference calibration curve from the calibration curves pertaining to the various laboratories and the method for the computation of the distance between the single curves and the reference. Moreover, the advantages of the global evaluation of compatibility between calibration curves versus the point-to-point compatibility are discussed. - Keywords:
