Rebound
Impact tester, or Leeb hardness tester, only works properly, if the impact body
has a certain position in the guiding tube at the moment of impacting the test
surface.
In the normal position when testing flat samples, the spherical test tip is
located exactly at the end of the guiding tube. When testing spherical samples
with standard support rings, it is to be observed that the radii R of curvature
do not drop below the values indicated. Standard Support Rings:
The standard support rings are supplied with the impact device.
