[en] Tribological properties of since materials for friction pairs are nowadays part of the technological requirements they have a decisive influence on the useful life of these pairs. An essential parameter to be measured is the wear undergone by materials that is caused during their performance. These measures can be taken in both lab or field testing, but they can be also calculated. For this, the wear mechanism must be taken into account. In the present paper, an algorithm for the calculation of wear based on the main disperse recommendations from the specialized literature is given. (Author) 16 refs
