The HIWA 700 Abrasion testing machine conforms with DIN53516 and is used to evaluate the resistance of elastomers to frictional wearing. Abrasion tests to this testing standard are performed on samples of materials which undergo wear and abrasion during their normal working life (e.g. tyres , conveyor and drive belts , shoe soles) . 
In this test, standard sample is weared on a drum equipped with an abrasive paper sheet in the selected path with a specific length . The sample loading force is set by placing loading weights onto the sample holding assembly . If the sample should also be additionally rotated about its main axis during test , a toothed rack can be fitted to the equipment .
