3.1 of the 2008 edition); -- The definition of normal operation is modified (see 3.2; see

3.2 of the 2008 edition); -- The definitions of "boil switch off" and "reset time" are deleted (see

3.7 of the 2008 edition); -- The classification of electric kettles is added (see Chapter 4); -- The original Chapter 4 "Test conditions" is moved to 6.1 (see 6.1; see Chapter 4 of the 2008 edition); -- The requirements for normal use environment are added (see 5.1); -- The requirements for boiling water performance are modified (see 5.4; see

5.3 of the 2008 edition); -- The requirements and test methods for the reset time are deleted (see

6.3.3 of the 2008 edition); -- The requirements and test methods for the water out-of-spout performance are modified (see

5.6 and 6.6; see

6.5 of the 2008 edition); -- The classification limits and test methods of thermal efficiency are modified (see

5.8 and 6.8; see

6.7 of the 2008 edition); -- The classification limits and test methods for the whole machine life are modified (see

5.9 and 6.9; see

6.8 of the 2008 edition); -- The requirements and test methods for boil-dry power-off time are added (see

5.10 and 6.10); Performance requirements and measuring methods for electric kettles

1 Scope

GB/T 22089-2021 is the Chinese national standard on performance requirements and measuring methods for electric kettles, in the field of domestic and commercial equipment, entertainment, sport. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 26 November 2021 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 June 2022. Classification: ICS 97.040.50, CCS Y63. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document specifies the scope, terms and definitions, classification, requirements and test methods of electric kettles for household and similar purposes. This document applies to electric kettles for household and similar purposes with a rated voltage not exceeding AC 250 V. This document does not address safety requirements related to food contact materials.

3 Terms and definitions

The following terms and definitions apply to this document.

3.1 electric kettle A portable electric heating appliance that is used to heat water to boiling point or to a 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 °C~45 °C;

b) Relative air humidity. not more than 95%;

c) Power supply. rated voltage ±10%, rated frequency ±

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. DeltaC -- 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.
