In a DIN abrasion test, the specimen is secured into a sample holder (quick clamp), and then guided in a precise manner, with or without rotation, over a predetermined distance of either 20 m or 40 m. There is also a given load on a piece of abrasive paper that is mounted to a 150 mm diameter stainless steel rotary drum. The drum turns at a speed of around 40 rpm. Ultimately, the frictional loss is computed by comparing the weight of the test specimen before and after the test.
