Industrial fans -- Performance testing using standardized airways
This standard has been revised by ISO 5801:2017
ISO 5801:2007 deals with the determination of the performance of industrial fans of all types except those designed solely for air circulation e.g. ceiling fans and table fans.
Estimates of uncertainty of measurement are provided and rules for the conversion, within specified limits, of test results for changes in speed, gas handled and, in the case of model tests, size, are given.
