• Abstract:

  A fundamental element in the international metrological system, which makes it possible to relate any pair of measurements (measurement or metrological statements), is the traceability chain in metrology. A measurement result that cannot be traced to a national standard and therefore to the international metrological system cannot be trusted. Two commonly used procedures to ensure the traceability of measurements to the international metrological system are the calibration of measurement instruments and the inter-comparisons of laboratories, which allow reaching agreements between the measurement standards. In this work we illustrate the use of the statistical methodology in the traceability chain, in order to determine the accuracy and precision of the measurements.
