Abstract This study deals with the analysis and usefulness of the material ratio curve. The parameters obtained from this curve are presented. The most popular of these parameters include two groups that are derived from this curve and provided in the ISO 13565–2 (Rk) and ISO 13565–3 (Rq) standards. They are compared by considering their practical significance and sensitivity to measurement errors. The parameters in the Rk family can easily be calculated but are ambiguous, which leads to errors in their calculation. The Rq group, which is based more on theoretical logic, must be applied with great care because of the problems with the Rpq parameter calculation and approximation of the material ratio probability plot. The methods of obtaining the correct oil capacity and its relation with the transition point between the central and valley surface parts are presented. The application of the material ratio curve in low-wear assessment is discussed.
