In this paper the description of an inter-laboratories comparison between the National Institute of Metrological Research (INRIM) and nineteen Italian Secondary Calibration Electrical Laboratories, is given along with its main results in graphical way. The transportable standards were three Tinsley four terminal standard resistors to be calibrated in oil respectively at 5 A and 20 A (1 mΩ), 1 A and 5 A (10 mΩ), 0.1 A and 1 A (100 mΩ). The comparison results were satisfactory, except only in a case of a Laboratory for which these measurements were outside its accreditation fields.
