  • Abstract:
    In the present work, part of a large project, developed in partnership among INMETRO, ITUC/PUCRio and INT since 1995, to establish a national hardness metrological system in Brazil to Brinell, Vickers and Rockwell hardness scales, is presented, e.g. the development of reference blocks, for different ranges of Rockwell B and C hardness scales. These results and the installation of a hardness standardization machine and an indenter calibration system at INMETRO will fill the existing voids up in the Brazilian traceability chain in hardness metrology.
