working principle is that under some specific load and on sand cloth of a specific grade,the column-shaped sample is placed on the sand cloth for abrasion for a specific journey.In this way ,the mass of the abrasion from the sample can be measured.With this and the demsity of the sample,the abrasion volume can be calculated. In order to make comparison,standard rubber is required at the end;and the test result shall be expressed as the relative abrasion volume with sand cloth as the benchmark or as the wear resistant index to a specific standard rubber.
