- Abstract:
- This paper presents the results of a bilateral comparison in torque measurements between NMISA in South Africa and INMETRO in Brazil. For this comparison, NMISA used a 20 kN·m torque comparator machine with a proposed uncertainty of 0.03 % (k = 2) across the entire measuring range. INMETRO used a 3 kN·m lever deadweight standard machine with uncertainty of 0.01 %. The comparison was conducted for both clockwise and counter-clockwise directions. Comparison analysis considered measurement data in the range of 200 N·m to 1 000 N·m. The maximum relative deviation observed for the bilateral is 2 × 10-4 in both directions.
