Force Standards Comparison between Mexico and Brazil

摘要

A force comparison was carried out between Brazil and Mexico, in order to estimate the level of agreement for the realisation of the quantity. The comparison participants were two secondary laboratories (CETEC and IPT/SP) and the national metrology institute (INMETRO) from Brazil and the national metrology institute (CENAM) from Mexico. The comparison was carried from 20 kN to 150 kN, using two load cells as comparison standards, having 1·10~(-5) relative repeatability each. Resumes of the general guidelines and procedure used for the comparison as well as the results obtained, deviations Figure for each participant laboratory are here included.
