家用和类似用途的舒适风扇和调节器 性能测量方法

[中文适用范围]： 本国际标准规定了家用及类似用途的舒适风扇及其调节器的性能测量方法，包括常规风扇、塔式风扇和无叶风扇，其额定电压对于单相风扇不超过250 V，对于其他风扇不超过480 V，其额定输入功率小于125 W。 [外文原描述]： 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.
