Scope

This Standard specifies the minimum allowable values, energy efficiency
grades, evaluating values of energy conservation, test methods, inspection
rules and energy efficiency grade marking for household and similar purposes
A.C. electric ventilating fans (hereinafter referred to as ventilating fans).
This Standard is applicable to AC motor-driven ventilating fans, of which the
single-phase rated voltage is not more than 250 V, the rated input power not
more than 500 W, and the impeller diameter is not more than 500 mm.
This Standard does not apply to ventilating fans for the following purposes:
a) ventilating fans that are specially designed for industrial use;
b) ventilating fans that are intended for use in special conditions, such as
places where there are corrosive, flammable, explosive gases, dust,
steam or coal gas;
c) ventilating fans for air heaters, freezers or air conditioners and air-to-air
energy recovery devices;
d) ventilating fans that are embedded in appliances such as stoves and
microwave cooking appliances;
e) marine ventilating fans;
f) type-C ventilating fans, two-way air-out fans, and type-B and type-D
ventilating fans of which the maximum static pressure is less than 25 Pa.
