The abrasion resistance of vulcanized rubber or other rubber compounds is tested using GenNBS. It is frequently used for shoe heels and soles. It has a sophisticated power failure recovery system. The instrument performs measurements through the volumetric loss of samples subjected to the action of a standardized abrasive media secured to a rotating cylinder.

There are at least 25 lab abrasion test equipment options. This is a blatant sign that it is difficult to connect this kind of testing to service performance. The National Bureau of Standards (NBS) Abrader is the most extensively used testing tool in the rubber industry. It is an abrader of the slinging variety. The NBS abrader operates at a steady velocity while applying a predetermined abrasive grit to a fixed load.

It won’t demonstrate how a certain molecule will function in highly variable circumstances. It won’t reveal anything about the material’s ability to resist cuts, flat spots, or chunking either.
