A tribological test is adopted to estimate the kinetic friction coefficient of the material of interest according to the ASTM standard. Typically a number of replicate is necessary to take into account the observed casual variability of the measurand as well as a post-processing data treatment is recommended. The paper describes a novel statistical approach aiming to highlight the most significant time intervals during each test replicate. Experimental activity has been carried out with reference to the ball-on-flat configuration of the tribo-meter in order to verify the suggested procedure in terms of both accuracy and reliability.
