European Standards,
as for example the EN 12413 “Safety requirements for bonded abrasives products” and
EN 13236 “Safety requirements for super abrasive products”
stipulate legally binding safety parameters for grinding
tools.
The testing procedure for grinding tools, included in
these norms, were developed in cooperation with the former
DSA (German grinding wheels committee) and mainly
by the MPA Hannover, for example for hand-held grinding
wheels, for tests of centrifugal force, side-load and testing
the working capacity with a drop hammer.
In the “Centre of Competence for Abrasive Tools (CCA)”,
the common laboratory of the MPA-Hannover and of the
Institute for metal forming and forming machines (IFUM) of
the Leibniz University
Hannover, all types of tests for rotating
grinding wheels with a diameter of 80 mm to 1600 mm and a
weight of 660 kg are performed. The testing
equipment of the CCA also serve as the
scientific exploration of rotating grinding tools Many, partially publicly funded research projects (eg. of the DFG, VDS, AIF) and publications have contributed not only to expanding the knowledge of rotating grinding tools, but also to developing new testing methods.
