- Abstract:
- In 2001, in order to improve the confidence level and the accuracy of the torque calibration systems in Brazil, the Force, Torque and Hardness Laboratory (Lafor/Inmetro) acquired a Torque Primary Standard Machine from 20 N·m up to 3000 N·m of nominal range, in clockwise and in anti-clockwise, where it was qualified by PTB/Germany in 2004. Since them, some steps have been done to disseminate the improved torque results to the users. The present work has the objective to demonstrate how Inmetro/Lafor is preparing to manage the torque metrology in Brazil due to the best measurement capabilities obtained and the increasing of the demand by the accredited laboratories and industries which are upgrading their torque equipment in order to get better uncertainties together with decreasing measurement costs.
