BS ISO 17713-1:2007

This standard BS ISO 17713-1:2007 Meteorology. Wind measurements is classified in these ICS categories:

• 07.060 Geology. Meteorology. Hydrology
• 17.080 Measurement of time, velocity, acceleration, angular velocity

1.1 This part of ISO 17713 describes wind tunnel test methods for determining performance characteristics of rotating anemometers, specifically cup anemometers and propeller anemometers.

1.2 This part of ISO 17713 describes an acceptance test and unambiguous methods for measuring the starting threshold, distance constant, transfer function and off-axis response of a rotating anemometer in a wind tunnel.

Note that when transferring values determined by these methods to atmospheric flow, there is a difference between anemometer performance in the free atmosphere and in the wind tunnel.
