Scope and application

This standard is, in principle, applicable to all types of wind turbines and rotor blades, even though many requirements have been formulated specifically for blades made from fibre-reinforced plastics for operation on horizontal axis wind turbines.

This standard is applicable to the structural and functional design, and manufacturing, of rotor blades for wind turbines, including requirements for materials, testing, repair and operation.

Rotor blades shall be designed so that:

— the maintaining of normal operational conditions will be ensured

— the safety of personnel and installations will be ensured and risks of injury to human life will be reduced to a minimum

— the rotor blades will reach the expected life time

— sufficiently high reliability is reached for the entire system.
