The work of preparing International Standards is normally carried o
11、ut through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO c
12、ollaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International
13、 Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elemen

16、:07 GMT+00:00 2007, Uncontrolled Copy, (c) BSI v Introduction Cup and propeller anemometers are the most frequently used meteorological instruments for the measurement of mean wind speed in the near surface layer, that portion of the atmosphere which lies within a few tens of meters of the earths su
17、rface. Some types of cup and propeller anemometers are available for measuring wind speeds of a few tenths of a meter per second while other types can measure wind speeds approaching 100 ms1. These general purpose anemometers are used extensively for meteorology, aviation, air pollution, wind energy
18、 and numerous other applications. This part of ISO 17713 was developed in order to have a worldwide uniform set of test methods to define the characteristics of cup and propeller anemometers. This part of ISO 17713 will allow an end user to compare different manufacturers and different models of cup
19、 and propeller anemometers to determine the suitability for a particular application.

21、cs 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 tunn
22、el. 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. 2 Normative references The following referenced documents are indispensable for the application of this document
