Abstract

The present paper describes the results of the bilateral comparison carried out between the CENAM (Mexico) 150 kN force standard machine and the INRiM (Italy) 1 MN Force standard machine. The two dead weight machines, their main metrological characteristics and the procedures of the comparison are described. Three different load cells (50 kN, 100 kN and 200 kN capacity) were used as transfer standards, and the test was made at 2 different load levels and at 5 angular positions for each load cell. The main results of the comparison with the relevant uncertainties from the measurements carried out at CENAM and at INRiM are presented and a final evaluation of the agreement between the two National force standard machines is given.
