BS EN IEC 61400-27-1:2020

What is BS EN IEC 61400 ‑ 27-1 about?

BS EN IEC 61400 ‑ 27-1 is a part of multi-series standard IEC 61400. BS EN IEC 61400-27-1 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. BS EN IEC 61400 ‑ 27-1 provides the detailed basis for fulfilling the current requirements of the IECRE system, as well as other IEC standards relevant to wind turbine blades, with respect to certification. When used for certification, the applicability of each portion of this document should be determined on the basis of the extent of certification, and associated certification modules per the IECRE system. Note 1: BS EN IEC 61400 ‑ 27-1 is intended to be applied to rotor blades for all wind turbines.
