SIM force standards comparison up to 10Â kN

A comparison in the quantity of force was carried out among the Interamerican Metrology System (SIM) national laboratories in order to estimate the level of agreement for the realization of the quantity and the uncertainty associated to its measurement. This comparison was carried out up to 10 kN. The equipment used consisted on two force transducers (load cells); both with the same measuring range (10 kN). With the purpose of obtaining maximum accuracy on the transducers, the comparison range was selected from 4 kN up to 10 kN. This comparison (SIM comparison number SIM 7.7) has an overlap with the force steps used in the CIPM key comparison CCM.F-K1.a and CCM.F-K1.b. The results obtained, as well as the reference values selected for the comparison are included in this document. Two different methods were used to analyze the level of agreement and to state the conformity declaration.
