1 Scope
This document specifies the energy efficiency grades, technical requirements,
test methods and energy efficiency calculation methods for electric fans.
This document applies to AC or DC motor driven table fans, louver fans, wall
fans, floor fans, pedestal fans and ceiling fans, of which the single-phase rated
voltage does not exceed 250 V and other rated voltages do not exceed 480 V.
2 Normative references
The contents of the following documents constitute the indispensable clauses
of this document through normative references in the text. For dated references,
only the version corresponding to that date is applicable to this document; for
undated references, the latest version (including all amendments) is applicable
to this document.

3 Terms and definitions
Terms and definitions determined by GB/T 13380-2018, GB/T 35758-2017 and
QB/T 5262-2018, and the following ones are applicable to this document.
3.1
Energy efficiency for electric fans
The ratio of the output air volume to the input power of the electric fan.
3.2
Minimum allowable values of energy efficiency for electric fans
The minimum allowable value of energy efficiency for electric fans under the
test conditions specified in the standard, on the premise of meeting the standby
power requirements.
3.3
Standby power
The power when the electric fan is switched on and in a waiting state (the motor
is not working).
3.4
Wind gathering fans
Table fans, wall fans, floor fans and pedestal fans whose ratio of the air volume
of the inner circle to the air volume of the outer circle is not less than 0.9.
4 Energy efficiency grade
The energy efficiency grade for electric fans is divided into 3 grades, of which
grade 1 has the highest energy efficiency. The energy efficiency value of
products of each specification shall meet the requirements of Table 1; its
standby power (if applicable) shall meet the requirements of Table 2.
