There　is　an　increasing　demand　for　the　large-scale　force　standard　machine　with　a　capacity　higher　than　20　MN.　In　this　paper,　the　calibration　method　and　procedure　were　developed　according　to　a　proposed　traceability　route　and　used　to　calibrate　a　60　MN　force　standard　machine.　One　7.5　MN　and　six　20　MN　force　transducers　and　two　60　MN　build-up　systems　were　used　as　the　force　transfer　standards.　Uncertainty　models　of　the　build-up　system　and　force　standard　machine　were　also　developed.　The　calibration　results　show　that　it　is　possible　to　calibrate　a　60　MN　build-up　force　standard　machine　with　a　relative　expanded　measurement　uncertainty　smaller　than　0.035%　(k　=　2)　by　two　build-up　systems,　which　were　compared　with　themselves.　The　60　MN　build-up　system,　which　worked　as　the　force　transfer　standard,　should　be　calibrated　to　confirm　its　systematic　error　and　corrected　by　the　error.　Its　uncertainty　also　could　be　estimated　independently　by　the　developed　model.　©　2020,　Metrology　Society　of　India.
