The integrity of fan data

Where comparisons of fan efficiency are to be made, it is es­sential that all data is the result of tests. These should be con­ducted to the same standard and test method. Individual wit­nessed tests are usually only possible after manufacture is complete and are very expensive. The purchaser should seri­ously consider if certified ratings in accordance with schemes such as AMCA211 will give the desired assurance (see Chap­ter 17, Section 17.11.2).
