The objectives of this standard are to: — Provide an internationally acceptable level of safety by defining minimum requirements for rotor blades of wind turbines (in combination with referenced standards, recommended practices, guidelines, etc.). — Serve as design basis for designers, suppliers, manufactures, purchasers and regulators. — Specify requirements for wind turbines subject to DNV GL certification. This DNV GL standard provides principles and technical requirements for rotor blades for wind turbines onshore and offshore. This DNV GL standard can be applied as part of the technical basis for carrying out DNV GL type certification of wind turbines, or DNV GL component certification of rotor blades. Guidance note: This standard covers the technical requirements to be applied for the DNV GL certification schemes. It is also intended for application in connection with IEC 61400-22 related certification schemes. ---e-n-d---of---g-u-i-d-a-n-c-e---n-o-t-e--- This DNV GL standard is intended to be applied in its entirety. Nevertheless, certain parts of it may be omitted if the applied certification scheme allows for such reduction in scope, and provided this is properly documented as a part of the certification process. Guidance note: For example, it may be acceptable to exclude the root attachment bolts from the scope of a component certification. ---e-n-d---of---g-u-i-d-a-n-c-e---n-o-t-e--- All requirements specified in this standard shall be fulfilled. Deviations from these requirements, or the application of alternative means of complying with these requirements, may be acceptable after consultation and agreement with DNV GL, provided that an equivalent level of safety and reliability can be demonstrated.
