Results of the performance evaluation of a newly designed, developed and fabricated dead weight machines to realize forces in the range of (2–50) N are reported in this paper. Precision load cells of 20N, 50N and 100N having an expanded uncertainty of ± 0.03% are used for this evaluation. The calibration of these load cells against the dead weight force machine shows that the repeatability (Rep) and reproducibility (Repr) are better than 0.003% and 0.005% respectively, over the entire range. The calibration data observed is found to closely agree with the calibration results obtained directly against the Physikalsich-Technische Bundesanstalt (PTB), Germany force standard machine having the relative measurement uncertainty of the force scale in the measuring range ≤ 0.002%.
