Abstract − In order to improve the metrological characteristics of the 110 kN INTI primary Force Standard Machine (FSM), an evaluation of the parasitic components that could rise for misalignments and structural deformations, is useful. The values of the parasitic components in static and dynamic conditions were determined by using the sixcomponent dynamometer property of CENAM. On the basis of the multi-component analysis and in order to reduce the effect of the parasitic components on the main axial load, a verification of the main frame inclination, of the load eccentricity and of the weight pieces misalignment was carried out. After some FSM structural correction, tests of repeatability and reproducibility were carried out to verify the parasitic components decreasing. 2. THE INTI´S 110 kN PRIMARY FORCE STANDARD MACHINE The INTI´s primary FSM is a GTM K-NME 110 kN, with the following characteristics: 110 kN maximal capacity, 2 kN lowest load, 3 columns loading frame, a
