Minimum allowable values of energy efficiency and
energy efficiency grades for household and similar
purposes A.C. electric ventilating fans
1 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.
2 Normative references
The following documents are indispensable for the application of this document.
For dated references, only the dated version applies to this document. For
undated references, the latest edition (including all amendments) applies to this
document.
GB/T 1236, Industrial fan. Performance testing using standardized airways
GB/T 2828.1, Sampling procedures for inspection by attributes. Part 1:
Sampling schemes indexed by acceptance quality limit (AQL) for lot-by-lot
inspection
GB/T 2829, Sampling procedures and tables for periodic inspection by
attributes (apply to inspection of process stability)

similar purposes
3 Terms and definitions
Terms and definitions determined by GB/T 14806 and the following ones are
applicable to this document.
3.1 Energy efficiency values for ventilating fans
Under the standard test conditions, the ratio of the measured air volume of the
ventilating fan to the measured input power of the fan blade drive motor, in cubic
meters per watt [m3/(min·W)].
3.2 Minimum allowable values of energy efficiency for ventilating fans
The minimum energy efficiency value for ventilating fans that is allowed under
the standard test conditions, in cubic meters per watt [m3/(min·W)].
3.3 Reach minimum allowable values of energy efficiency for ventilating
fans
The minimum allowable values of energy efficiency for ventilating fans that is
implemented after several years of implementation of this Standard.
3.4 Evaluating values of energy conservation for ventilating fans
The minimum energy efficiency index that an energy-conservation ventilating
fan shall achieve under standard test conditions, in cubic meters per watt
[m3/(min·W)].
4 Technical requirements
4.1 Basic requirements
The performance of the ventilating fans to which this Standard applies shall
comply with the requirements of GB/T 14806.
4.2 Energy efficiency grades for ventilating fans
requirements in GB/T 1236. If there is any dispute over the test results, test and
determine according to the method that is specified in GB/T 1236.
6 Inspection rules
6.1 Delivery inspection
6.1.1 The inspection plan which refers to GB/T 2828.1 and GB/T 2829, shall be
carried out by the manufacturer's quality inspection department in accordance
with relevant enterprise standards.
6.1.2 Products whose energy efficiency values are recognized, through
inspection, to be inconsistent with the requirements of 4.3 are not allowed to be
delivered.
6.2 Type inspection
6.2.1 When any of the following conditions occurs, the type inspection of
minimum allowable values shall be carried out:
a) new products that are trial-produced;
b) when the product design, process or used materials are changed to
significantly affect its performance;
c) when inspection requirements are put forward by the quality and technical
supervision department.
6.2.2 For sampling of type inspection, 3 machines shall be sampled at a time,
one for testing and two for standby application. If the test result does not meet
the specified requirements, test the two standby samples; the measured values
shall meet the specified requirements; otherwise, the batch of products shall be
judged as unqualified.
7 Energy efficiency grade marking
7.1 The manufacturer shall determine the rated energy efficiency grades of the
product in accordance with the requirements of this Standard and the test
results.
7.2 The manufacturer shall indicate the rated energy efficiency grade of the
product and the standard number on which it is based on the product
documentation of its product.
