A PROPOSAL OF AN EVALUATION METHOD OF UNCERTAINTY IN THE TRACEABILITY SYSTEM OF FORCE

  • Abstract:
    This paper proposes a new approach for evaluating the uncertainty in the traceability system of force with the following features. a) Repeatability/reproducibility is evaluated by the Type A evaluation. b) Data taken in each orientation is treated with equality. c) Deviations from reference values and from the interpolation equation are considered to be equal to the standard deviation 1s of a normal distribution. d) Difference of the values in increasing load and in decreasing load are considered as a half-width of the possible distribution of values to be measured. The same is the case of difference of the zero points in a loading cycle.
