It is a device designed for accelerated material wear tests. The test consists in mounting a flat sample on a movable platform, which rotates around its axis at a given speed. Two abrasive discs are lowered onto the surface of the test sample and pressed with appropriate force. The wheels turn in opposite directions and make a full circle on the surface of the sample. This system allows the abrasion resistance of the material to be tested in every direction, regardless of the structure, weave or grain pattern in the material.
The apparatus is designed to test the resistance of materials and products to surface abrasion and to assess the relative strength or susceptibility of the material surface to physical damage such as wear and abrasion, scratching, gouging, scratching, abrasion, color transfer (usually called color fastness) and others.
The linear abrasion tester can be used for both dry and wet tests. It is designed to test samples of virtually any size and shape.
