This International Standard specifies the performance-measuring methods of comfort fans and regulators for household and similar purposes, including conventional fans, tower fans and bladeless fans, their rated voltage being not more than 250 V for single-phase fans and 480 V for other fans, and their rated power input being less than 125 W.

NOTE 1 According to the testing method, the comfort fans are classified into two groups:

  • pedestal fans, table fans, wall fans, louvre fans, tower fans, bladeless fans;

  • ceiling fans.

Wherever applicable, the term “fan” used in this document includes its associated regulator, if any.

NOTE 2 This document does not apply to

  • safety of electric fans for household and similar purposes (IEC 60335-2-80);

  • performance of ventilating fans (IEC 60665);

  • electromagnetic compatibility of fans (CISPR 14-1 and CISPR 14-2, IEC 61000-3-2, IEC 61000-3-3).
