In the industrial sector, metrology allows to support the quality of the processes, because, in all these, physical quantities intervene that influence each stage of these and whose effects are reflected in the quality of the final product. These quantities must be measured to take control actions and ensure that their effect will not be negative on the requirements of the products. Measuring instruments, as well as the metrological reliability of their calibration, based on the use of software and computerized systems, become major challenges for industrial metrology. In that order of ideas, the main objective of this work is to explain the methodology for the design of software that allows generating calibration certificates in thermal metrology. The work was motivated due to challenges imposed by Accredited Laboratories to optimize their processes. The methodology adopted, based on the programming of computational algorithms in a C-Sharp language (C #) made it possible to: (i) perform a complex uncertainty analysis (GUM); (ii) estimate the adjusted calibration curve from the consecrated theory of ordinary least squares and (iii) validation from real experimental data. The consolidated results allowed us to conclude that the software developed is aligned with the requirements of ISO / IEC 17025: 2017, in addition to being an effective tool for increasing the metrological reliability of industrial processes, thus contributing to the advancement of knowledge in the metrology.
