Page 11: The Leeb Test Principle
3.2 The LEEB test principle The basic principle is to use a rebound body of a specified weight, which is impacted on the test surface using a specified test force and then the impact velocity and rebound velocity of the rebound body are measured with the spherical test tip 1mm above the surface to be tested. -

- Weighing down the test piece: this is not necessary for heavy test pieces. Medium- heavy objects are placed on a smooth and stable surface. The test piece should be placed absolutely flat and without wobbling. - A sufficient material thickness of the test piece is required, as well as the minimum material thickness. - Page 14 Localization The support ring of the rebound sensor is now pressed firmly onto the surface of the test piece, whereby the rebound direction should always be vertical to the surface to be tested. Testing - For testing, the release button on the upper side of the rebound sensor is pressed. It is assumed that the test piece as well as the device are in a fixed position at this time.
