TUV Rheinland has been accredited by the German Accreditation Body (DAkkS) as a certification body for type and component certification of wind turbines in accordance with international standard IEC 61400-22.
This authorizes the company to conduct conformity assessments of onshore and offshore wind turbines and their components, and to issue certificates accordingly.
The certification process comprises several steps. Based on the turbine design, it includes a comprehensive assessment of the construction documents; evaluation of the manufacturing process, including quality management; and prototype testing by neutral experts.
Among others, the tests cover design requirements and safety-related issues, as well as the design of turbines, gear systems and rotor blades. Optional assessments of the foundations and additional measurements can be conducted. After a final evaluation, the process is completed with the issuance of the appropriate certificate to the manufacturer.
