IEC 60879:1986/COR1:1992

IEC 60879:2019 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. 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. 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). This second edition cancels and replaces the first edition published in 1986. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the definitions of fans have been revised; b) the test methods for the different types of fans have been revised to allow modern test instrumentation to be used; c) acoustic noise measurement and standby power measurement methods have been introduced.
