CCM.T-K2

MEASURAND: Torque

NOMINAL VALUE: 10 kN.m clockwise torque

 

Two different torque transducers, TB2 and TT1, were used for the comparison. The Key Comparison Reference Values xR and corresponding uncertainties uR were determined for each transducer and are listed below. However, the Degrees of Equivalence were calculated based on the mean value of the results obtained using both transducers.

Transducer xR / kN·m uR / N·m
TB2 clockwise 10.000 0.2
TT1 clockwise 10.000 0.3

 

For each torque the degree of equivalence of laboratory i with respect to the key comparison reference value xR is given by a pair of terms: Di and its expanded uncertainty Ui (k = 2) both expressed in N·m. The computation of Di and Ui is explained in the CCM.T-K2 Final Report.
