Abstract

The present invention relates to a tribometer (1) comprising: a first support assembly (2) configured to receive a central test piece (3), which test piece is circularly cylindrical, and to drive it in rotation about its axis (X); and a second support assembly (4) configured to receive a plurality of peripheral test pieces, preferably three of them, and to enable said central test piece (3) to make contact simultaneously with said three peripheral test pieces (9) in an isostatic configuration in such a manner that the central test piece, while being driven in rotation, can rub against the peripheral test pieces.
