This document is the collection of the individual reports of the laboratories which participated in the intercomparison campaign. A synthesis report is published full size with the same title. An intercomparison of resistance standards at 10 and 1 kohm has been carried out on four resistors by 7 international metrological laboratories, where measurements were made in terms of the local standards. The objective was to assess how well an intercomparison of this type, which involves considerable travelling on the part of the resistors, could be carried out. The typical standard error of the linear fit to all data is 0.2 ppm. Almost all the measurements were within two standard deviations of the uncertainties claimed by the participating laboratories. As a result it can be stated that resistors of the type used are suitable for intercomparing the primary national laboratory standard at the level of uncertainty quoted above.
