หลักการ

Under a predetermined contact pressure and a given area ,the specimen with sandpaper angled to measureabrasion resistance of the specimen subjected to rubbing on a certain level of sandpaper, sandpaper affixed to the surface of the drum, samples pressed on a drum with sandpaper, and the specimen along the roller to the lateral movement, abrasion resistance is produced at one end of the cylindrical specimen, tests the value of the mass loss of the specimen, by the density of the specimen to calculate the amount of volume abrasion.

DIN ISO 4649:2006-11 (จ). Rubber, vulcanized or thermoplastic – Determination of abrasion resistance using a rotating cylindrical drum device.

ASTM D5963 – 04(2010)e1 Standard Test Method for Rubber Property—Abrasion Resistance (Rotary Drum Abrader).
