Resumen:
This international standard deals with the classification of fan efficiency for all fan types driven by otors of nominal rating 0.125 kW and above. This standard may be used by legislators or regulatory bodies for defining future energy saving targets. This applies to the fan (driven) only but not to the system (finished Original Equipment Manufacturer's product, e. g. box fans and roof fans or ventilation system) in which it is installed.
