The IEA developed international recommended practices for development and testing wind turbines, and the International Electrotechnical Commission Technical Committee 88 (IEC-TC88) and other agencies are developed international norms and standards. As countries adopted these new standards, the IEA suggested that a mechanism be in place to ensure that turbines are tested and certified to common criteria.
A series of round robin comparison tests at participating national laboratories and other interested test stations were suggested as a means of validating test procedures and establishing reciprocity between different certification testing laboratories. The objectives of this program were to:
- Validate wind turbine testing procedures
- Analyze and resolve sources of discrepancies
- Improve testing methods and procedures
