Taberabrasjonstest

Taberabrasjonstest, or Taber abrasion test, is a widely used method for evaluating the wear resistance of materials. It measures how much material is removed when a sample is subjected to repeated rubbing against abrasive wheels under a defined load. The test uses a Taber Abraser instrument, where the specimen is clamped to a turntable. Two abrasive wheels are pressed against the sample by calibrated weights while the turntable rotates. The test can run for a defined number of cycles or until a specified criterion is reached. After testing, the specimen is cleaned and weighed, and wear is reported as mass loss (milligrams) or thickness loss, sometimes as a wear index. For textiles and floor coverings, changes in appearance and thickness loss are common reporting measures.

Applications: The method is used for coatings, polymers and composites, textiles, leather, rubber, and floor coverings to compare wear resistance and to support quality control and product development. The choice of wheels and abrasives, load, speed, and cycle count depends on the material and standard used. For textiles, common wheel types and abrasive media are specified in relevant standards; for coatings, interactions between the film and substrate are captured.

Standards: Numerous national and international standards govern the Taber abrasion test, including guidelines published by ASTM International and ISO organizations. They specify apparatus, wheel type, loads, speeds, cycles, conditioning, sample preparation, and reporting.

Limitations: Results depend on test conditions and wheel-media pairing; thus, they provide comparative durability under simulated rubbing rather than an universal measure of real-world wear.
