DIN ISO 17713-1:2007-10

This International Standard defines standard test methods which describe the dynamic performance of wind vanes and rotating anemometers. This standard does not include environmental testing for operational applications. Measurement of wind speed and wind direction are required for many applications. The standard provides performance specifications for anemometers which include starting threshold, distance constant, transfer function, and off-axis response. For the wind vane they include starting threshold, damping ratio and transfer function.
