Schob Abrasion Tester

The Schopper abrasion tester applies pressure and friction to the specimen by rotating a grinding wheel, simulating the wear process on the material surface. It is used to test the abrasion resistance of materials such as paper, coatings, and plastics, and to evaluate product durability in quality inspection and research and development.
Selection
When selecting, consider the compatibility with testing standards, such as national standards or ISO; sample dimensions must fit the fixture; the load range should cover actual usage conditions; adjustable rotation speed to accommodate different materials; and a sturdy equipment structure to ensure test repeatability.
