Abrasion tester
Model 5135 / 5155 Taber Industries

The TABER® Rotary Platform Abrasion Tester – Model 5135 or 5155 is commonly referred to as the Taber Abraser (Abrader). This precision built instrument was developed to perform accelerated wear testing and is capable of providing reliable data in a matter of minutes compared to the years that may be required by in-use testing. Used to test a wide spectrum of materials, the instrument has been referenced in numerous standards and specifications (including plastics, coatings, laminates, leather, paper, ceramics, carpeting, safety glazing, etc.).

Taber tests involve mounting a flat specimen approximately 100mm square or round (and typically less than 12.5 mm thickness) to a turntable platform that rotates on a vertical axis at a fixed speed. Characteristic rub-wear action is produced by contact of the test specimen against the sliding rotation of two abrading wheels. As the turntable rotates, the wheels are driven by the sample in opposite directions about a horizontal axis displaced tangentially from the axis of the sample while a vacuum system removes loose debris during the test. The wheels traverse a complete circle on the specimen surface, revealing abrasion resistance at all angles relative to the weave or grain of the material. The resulting abrasion marks form a pattern of crossed arcs in a circular band that cover an area approximately 30 cm2.
