Abstract

A torque comparison was carried out between the Centro Nacional de Metrología, CENAM (in Mexico) and the Instituto Nacional de Metrologia, Normalização e Qualidade Industrial, INMETRO (in Brazil), in order to estimate the level of agreement for the realization of the quantity and the uncertainty associated to its measurement. The comparison was carried out in a range starting at 20 N·m and up to 100 N·m. The results obtained, deviations graphs (including the uncertainty for each torque applied of each laboratory) and the normalized error equation application results are presented in this document. This constitutes the first torque comparison within the Sistema Interamericano de Metrologia (Interamerican Metrology System, SIM) and has the classification number SIM.7.27 BK.
