Test Results

Test Certification according to § 47a StVZO
regarding the tests that have been carried out according to the rules and regulations valid in the countries of the European Community, based on the DIN/ISO norms as used in the testing facilities.
In order to give an image about the performances, several tests have been carried out on specialized independent test benches. There have been tested both older and newer car types, in order to cover most of the usual vehicles.
The values before and after are to be understood as before and after mounting the ProMag.
