The ASTM D4060-19 standard measures the abrasion resistance of organic coatings with the Taber abrasion tester. Designed to simulate accelerated abrasion conditions, this test method is widely used in testing and specifications for a wide variety of products worldwide. The testing process involves mounting the sample on a swirl/spin turntable so that the grinding wheel applies abrasion to the surface of the sample until coating failure or substrate exposure. The standard specifies parameters used in the test, such as number of cycles, load, and type of abrasive wheels, to ensure accuracy and comparability of test results. The ASTM D4060 is suitable for flat and rigid test samples to evaluate the wear resistance performance of coatings under the intended conditions of use.
