The MPA Hannover possesses the international accreditation  from DIN EN ISO/IEC 17025 for the testing of grinding  wheels and similar  products according to  EN 12413, EN 13236  and numerous other  international norms.  With this, the MPA  Hannover underlines  its position as  a leading European  Laboratory for rotating  grinding tools.
The test reports and security certificates, created by us,have gained international importance. Both German and  foreign manufacturers of grinding and cutting wheels,
have their products tested on a voluntary basis, to mark  them with a MPA certificate number. For well-known   international importers it is only a matter of course that  their products are tested by  us before they come on the  market.

enables  the MPA-Hannover to  examine, in particular
the rapidly expanding  Chinese market to comply with European safety standards.
Testing for Manufacturers  The international accreditation of the MPA Hannover as a
testing laboratory for grinding wheels and similar products,  gives the client security that our test results are  acknowledged and accepted worldwide as a safety proof.  Test reports provide information about in the examination  established safety parameters, such as bursting speed
(centrifugal test), single-point and/or three-point side load  and work capacity (hammer test) with bonded abrasive  wheels (e.g. EN 12413) or rather the centrifugal force and
the measured values for the bending strength of diamond
grinding wheels (EN 13236). On the basis of one or more
test reports the manufacturer can demand a MPA certificate,
in which the compliance of the tested products with  the corresponding norm is certified.
Testing for importers  Before the dispatch of the grinding wheels, spot checks
are taken and sealed up in the country of origin by commissioners  or rather employees of the MPA-Hannover, or neutral removal companies and then send to the MPA to be further tested. These samples are tested for compliance with the relevant standard security parameters. The
client receives a written test report that contains a summary of the test results and which serves as proof for a safety check, before the products go on sale.
Test for retailers and consumers On request, we also test rotating grinding tools that are
already on the market. Furthermore, we prepare reports for courts, insurances and labor inspectorates.尤其是迅速扩大的中国市场，以符合欧洲安全标准。 为制造商测试

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.
