user-set temperature value and then automatically cuts off the power supply; water can
be poured from its spout by holding the handle and tilting the kettle body.
3.2 normal operation
The electric kettle works under the rated voltage, with water filled into its container to
the nominal maximum water level and the lid closed; the electric kettle can heat the
water to the boiling point or the temperature set by the user and then automatically cut
off the power.
NOTE. If there are accessories such as dust covers and filters, install them according to the instructions.
3.3 rated capacity
The maximum volume of the kettle specified by the manufacturer.
3.4 boiling water
Water that has been heated to boiling temperature.
3.5 boiling water break time
Under specified test conditions, the time required from the time the water reaches
boiling temperature to the time the electric kettle automatically cuts off the power.
3.6 thermal efficiency
The ratio of the quantity of heat (Q) absorbed by the water when the temperature rises
to the electricity consumed in this process (E) measured under specified conditions.
4 Classification
According to the control method. mechanical and electronic.
5 Requirements
5.1 Normal use environment
The household and similar electric kettles specified in this document shall be able to
operate normally under the following environmental conditions.
a) Ambient temperature. 5 ℃~45 ℃;
b) Relative air humidity. not more than 95%;
c) Power supply. rated voltage ±10%, rated frequency ±1 Hz;
d) Altitude. not more than 800 m.
5.2 Volume deviation
The deviation between the actual volume of the electric kettle and the rated volume
shall not exceed ±5% of the rated volume.
5.3 Prompt function
The electric kettle shall have a prompt function for different working states, such as
heating and keeping warm, to remind the user of sound or light information.
ΔC -- Volume deviation, %;
C -- Actual capacity of the electric kettle, in liters (L);
CR -- Rated capacity of the electric kettle, in liters (L).
6.3 Prompt function
Observe whether it is qualified through visual inspection.
6.4 Boiling water performance
6.4.1 Boiling water cut-off temperature
Fix the thermocouple 10 mm above the center of the bottom of the electric kettle.
For the electric kettle with the heating element immersed in water, the thermocouple is
fixedly placed 10 mm above the highest end of the heating element.
Let the electric kettle work under normal working conditions, and measure the
corresponding water temperature when the temperature control device acts.
6.4.2 Boiling water break time
According to the test method in 6.4.1, measure the time from the water temperature
reaching 98 ℃ to the time when the temperature control device operates.
6.5 Lift-to-off function
Check whether it meets the requirements through observation and manual operation.
6.6 Water out-of-spout performance
6.6.1 Normal pouring test
The electric kettle is operated under normal working conditions until the temperature
control device is activated, and then the electric kettle is immediately lifted vertically
so that the spout is (5±1) cm above the upper edge of the water receiving container. The
kettle body is tilted and water is poured at the most unfavorable flow rate between the
minimum flow rate (water can be poured continuously) and the maximum flow rate (the
water level does not exceed the lowest point of the kettle lid) until all the water in the
kettle is poured out.
Pour half of the rated volume of water into the kettle and repeat the above test.
NOTE. When the bottle is nearly empty, some dripping and intermittent water flow are permitted.
6.6.2 Abnormal pouring test
