KEY COMPARISONS IN THE FIELD OF TORQUE MEASUREMENT
Dirk Röske
Abstract:
One of the main tasks of the National Metrology Institutes (NMIs), besides the realization and improvement of standards for the different physical and other quantities, is to carry out comparisons between their own standards and those of other NMIs. At the highest level, the CIPM key comparisons involve at least the standards with the smallest uncertainties of measurement in the world and should cover - if possible - all geographical regions through the corresponding Regional Metrological Organizations (RMOs). It is also intended to compare different realization techniques of the given quantity and to make a statement of equivalence for the different calibration capabilities. This document deals with the recently agreed CIPM key comparisons in the field of torque measurement.
