Compliance with certain guidelines and standards for products or services, such as the EC Machinery Directive, or the Guidelines of the Germanischer Lloyd for wind turbines are tested and certified. The certificates refer to specific standards and to specific products or services. Certification is a prerequisite for introducing products in the market quickly and effectively, and for developing serial production..  Certificates are a basic requirement for financing and insuring wind turbines.

At W2E, certification is acquired from accredited institutes.

For certification, the independent institute which provides the certificates is given extensive material consisting of model concepts, design documents, technical calculations and simulation results.

All mechanical, electrical and safety technology systems and components, the overall behaviour of the wind turbine in the wind and on the grid, the comprehensive qualified documentation and the start-up processes are tested in detail in terms of reliability and safety.

In preparation, load cases are calculated, FEM and multi-body simulation and drive train analyses are performed. The individual developmental stages of the wind turbine are completed by:

• C design assessment
• B design assessment
• A design assessment

W2E works with TÜV Nord as the recognized body for type testing, Germanischer Lloyd (GL) and the DEWI OCC as independent certifying bodies.
