3. DIN Abrasion Tester Working Principle
DIN Abrader(Abraser) consists of a rotating drum whose surface would be stick with sandpaper 60#. DIN Abrasion is one of the most common rubber abrasion test methods. Equipped with a rotational block, Unuo DIN abrasion machine can do both rotating and non-rotating tests.
Clamp the rubber sample on the specimen holder, the DIN abrasion machine would rub the sample on the drum under a certain inclination and a certain load. Then to measure the sample volume loss after rubbed for a certain distance.
4. How To Calculate Abrasion Resistance of Rubber / DIN Abrasion Test Results (ISO 4649 abrasion test for example)
4.1 Relative Volume Loss
- ∆mt : the mass loss, in mg, of the test rubber test piece;
- ∆mconst : defined as 200mg for method A using standard reference compound No. 1;
- Pt: the density, in mg per cubic millimetre , of the test rubber;
- ∆mr :the mass loss, in mg, of the reference compound test piece.
4.2 Abrasion resistance index, ARI
- ∆mr : the mass loss, in mg, of the reference compound test piece;
- Pt: the density, in mg, of the test rubber;
- Pr: the density, in mg, of the reference compound;
- ∆mt : the mass loss, in mg, of the test rubber test piece;

7. FAQ
What is a DIN abrasion test?
DIN abrasion test(ISO 4649/ ASTMD5963) is to test rubber and elastomer products wear resistance by rubbing a sample on a P60 sandpaper with a certain load like 5N, 7.5N or 10N. By comparing the abrasion loss with standard rubber, the sample abrasion resistance Relative Volume Loss & Abrasion resistance index, ARI can be calculated.
ISO 4649 VS DIN 53516 DIN Abrasion Test Method Comparison
DIN 53516 is replaced by ISO 4649. But there are still many industries using it. Generally speaking, this 2 DIN abrasion test methods have the same specification requirements for the DIN Abrader. The most obvious difference is ISO 4649 mentions 2 abrasion test methods – non-rotating or rotating while DIN 53516 has no clear requirements for this. Both standards are adopted to determine abrasion resistance of rubbers.
DIN Abrasion Rotating Method VS Non-rotating Method
The DIN abrasion rotating method would make the sample to be rubbed more uniform. But, the non-rotating is more commonly used.
