This work compared the guidelines established by the OIML R 76-1 and SIM Guide for Calibration of analog non-automatic weighing instruments. Once the data were obtained in the accredited metrological laboratory, the task of tabulating, calculating and then comparing, by means of statistical tools, the similarities, advantages and disadvantages among the four different calibration processes was performed. Comparing the results obtained for the different tests carried out, the results

(ii) reformulate the cost / benefit criteria for the calibration of scales, once it is known that better results can be obtained by the application of a particular method; (iii) analyze an unquestionable economic impact, since it constitutes a large part of the solution of technical-economic challenges such as the one mentioned above. In addition, the methodology used here can be recreated for another type of analog non-automatic weighing instrument and thus build a real contribution to the state of the art of mass metrology.
