As the only laboratory in France labeled MEASNET, and accredited by COFRAC, the CSTB guides professionals towards success in their projects involving the use of wind as a resource. This requires a reliable and accurate anemometer calibration. The specialists rely on their expertise in climatology, and on their cutting-edge equipment: special on-site sensors and a dedicated wind tunnel, known as the µSE wind tunnel, in Nantes (France).
The calibration of anemometers is performed at the CSTB’s µSE wind tunnel in Nantes, in compliance with the IEC 61400-12-1:2005/Appendix F standard and the MEASNET procedure. They are accredited in accordance with the NF EN ISO/CEI 17025 standard by COFRAC, the French national accreditation body. The scope is available on the website www.cofrac.fr, n°2-1930.
A precise and reliable measurement of wind speed is essential. Any variation in the estimated wind level can, indeed, have a very significant impact on the safety of people and property, or on the operating outcomes of a wind farm.
