Following is the detailed procedure for DIN abrader testing.

1. First, the abrasion sheet’s abrasiveness is determined. Once it is done, the device is now ready for testing. The test samples can be drilled easily on the rubber sheet or the final product using the circular cutting knife, which is optional. Usually, the tests are done at an ambient temperature of 230 C + or – 50 C with the option to heat the drum at a higher temperature.
2. The test specimen’s weight is initially measured.
3. The sample is next mounted onto the sample holder. Set the preferred abrasion distance and apply the load weights. The cover of the instrument is then put in place. The testing procedure commences by simply clicking on the tester’s start button.
   The drum will then begin to rotate, and the test specimen will be sent over the abrasion sheet. The moment the pre-determined abrasion distance is hit, the instrument will automatically stop running.
4. At the conclusion of the test run, the sample is taken out of the sample holder, then the weight of the test sample after the abrasion process is measured.
5. Calculate the abrasion. To do this, convert the mass loss (with average value of 3 – 10 individual values) into volume loss with the aid of the density and the correction done for the abrasion sheet’s abrasiveness deviation from the given value of abrasiveness.

The following formula is used:

Abrasion = mass loss x abrasiveness x 200 specific weight
