IEC 61400-12-1:2017
The IEC 61400-12-1 is the most important standard for wind measurement. This standard specifies the correct set-up of a met mast including installation of sensors. It describes the quality of sensors installed on the met mast with regard to accuracy and reliability. Additionally, it defines a set of criteria with regard to data quantity and quality.
In 2022, IEC 61400-12-1 was getting too big. For this reason it has been decided to split it in altogether 10 components.
So the IEC 61400-12-1:2017 “mother norm” is withdrawn, the work will be pursued in the 10 “daughter norm”:
- IEC 61400-12 -1 to -6 for measurement of wind turbine power
- IEC 61400-50-1 to -4 for the measurement of the wind speed
