TABER ABRASER

Born in the 1930s, the Taber Abraser was Ralph Taber’s rotary platform tester for accelerated wear; it became the company’s signature instrument when Taber Instrument Corporation was founded in 1941.
A pair of abrasive wheels are loaded off-centre on a rotating plate or disk, creating a repeatable 2-body abrasive wear mechanism. Particles are removed by a vacuum nozzle. By controlled cycles, the system reports performance as mass loss or optical haze.  Still a workhorse across coatings, plastics, flooring, textiles, leather, metals and more. Common benchmarks include ASTM D4060 (coatings, weight loss), ASTM D1044 (plastics, haze), ISO 5470-1 (rotating abrasion), and application-specific methods such as ASTM C1353 for stone flooring.

In short: not glamorous, but ruthlessly repeatable—and still the de facto yardstick for 2-body abrasion resistance.
