The Taber Abraser determines the abrasion resistance of all sorts of materials. The Taber Abraser test is an internationally standardized testing method. The abrasion load is created by two friction rollers that are pressed onto the rotating specimen with a defined force. A flat disc of the tested compound serves as specimen that has to be produced especially for the test in most cases. The rollers are not aligned precisely tangentially with the specimen. One of the two rollers exerts force outwards, the other towards the middle. The resulting abrasion marks form a pattern of crossed curves. On that way the surface is loaded isotropically. After testing the volume loss or mass loss is determined. Wear rates can be calculated in dependence of testing duration.
