This part of IEC 61400 specifies requirements to ensure the engineering integrity of wind turbine blades as well as an appropriate level of operational safety throughout the design lifetime. It includes requirements for aerodynamic and structural design; material selection, evaluation and testing; manufacture (including associated quality management); transportation, installation, operation and maintenance of the blades.
The purpose of this document is to provide a technical reference for designers, manufacturers, purchasers, operators, third party organizations and material suppliers, as well as to define requirements for certification.
With respect to certification, this document provides the detailed basis for fulfilling the current requirements of the IECRE system, as well as other IEC standards relevant to wind turbine blades. When used for certification, the applicability of each portion of this document should be determined based on the extent of certification, and associated certification modules per the IECRE system.
NOTE: US TAG ballots must be submitted prior to the IEC deadline to allow for resolution of any comments.
