IEC Standards

The IEC Technical Committee 88 on Wind Turbines is responsible for preparing international standards for wind turbines that convert wind energy into electrical energy. The standards cover design requirements, engineering integrity, measurement techniques and test procedures. Their purpose is to provide a basis for design, quality assurance and certification. The standards are concerned with all subsystems of wind turbines, such as mechanical and internal electrical systems, support structures and control and protection systems. They are intended to be used together with appropriate IEC/ISO standards.

IEC 61400 consists of the following parts under the general title Wind Turbine Generator Systems:
Part 1: Design requirements
Part 2: Small wind turbines
Part 11: Acoustic noise measurement techniques
Part 12-1: Power performance measurements of electricity producing wind turbines
Part 12-2: Power performance of electricity-producing wind turbines based on nacelle anemometry
Part 13: Measurement of mechanical loads
Part 14: Declaration of apparent sound power level and tonality values
Part 21: Measurement and assessment of power quality characteristics of grid connected wind turbines
Part 23: Full-scale structural testing of rotor blades
Part 24: Lightning protection

Other parts of the IEC 61400 are under preparation by IEC TC 88. A standard on the design requirements for offshore wind turbines is being developed by IEC TC 88.
