It is possible to convert the volume loss measurement into an abrasion resistance index %. A higher number on the index percentage denotes a better outcome and more abrasion-resistant rubber material. Other organizations’ standardized rubber abrasion resistance tests have also employed this testing procedure. These include the ISO 4649 test and the DIN 53516 test, which stands for “Testing of Rubber and Elastomers; Determination of Abrasion Resistance” (Rubber, vulcanized or thermoplastic – Determination of abrasion resistance using a rotating cylindrical drum device).

The level of resistance of abrasion-resistant rubber is affected by several properties of the material. The harder and denser the rubber is the higher its durometer. A high-durometer rubber will typically be more resistant to abrasions and indentation. Rubber’s tensile strength can potentially impact rubber’s resistance to abrasion significantly.
