Laboratory Berlin
Whether high-voltage, high-power or mechanics, every testing laboratory is accredited for the performance of internationally recognized type tests according to ISO/IEC 17025. We are a member of PEHLA (Gesellschaft für elektrische Hochleistungsprüfungen), which is associated with the international Short-Circuit Testing Liaison (STL).
Laboratory Nuremberg
From general basic research with high-voltage tests of different voltage types via dielectric investigations to tests with test setups specifically designed for use in electrical components, the Electrical Research and Testing Laboratory Nuremberg enables a wide range of tests and analyses.
Testing Laboratory Berlin
As accredited testing laboratories, we have been testing electrotechnical components for Siemens and Siemens Energy and external customers for over 90 years. We guarantee the impartiality and independence of all the tests we conduct for high and medium voltage. With our high level of technical expertise, we additionally offer tests for areas such as wind power and aviation as well as plant engineering and machine building. Thanks to our wide-ranging test portfolio, we are able to test materials of all kinds.
