BS EN IEC 60879:2019 pdf download.Com fort fans and regulators for household and similar purposes - Methods for measuring performance (IEC 60879:2019)
I Scope
BS EN IEC 60879 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 I 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
