Foreword
This Standard was drafted in accordance with the rules given in GB/T
1.1-2009.
This Standard replaces GB 12021.6-2008 Minimum allowable values of
energy efficiency and energy efficiency grades for automatic electric rice
cookers. Compared with GB 12021.6-2008, the main technical changes are
as follows.
- added the product of which the heating method is electromagnetic
induction heating in the scope;
- deleted the definition and requirements for “energy saving evaluation
value”;
- deleted sub-clause 4.1 in the previous edition (basic requirements);
- merged the original two power segments of 600W ~ 1000W product as
one power segment (see Table 1);
- improved the indicators of energy efficiency, thermal insulation and
standby power (see Table 1);
- provided a certain degree of compensation to electromagnetic induction
heating and energy efficiency of non-metallic pot products in thermal
efficiency calculation formula (see 4.2);
- only retained the contents of 6.2.2 in the previous edition in the
inspection rules; deleted the rest;
- changed the measuring method for the maximum temperature in test
methods (see A.2.1 of Annex A).
This Standard was proposed by Division of Resource Conservation and
Environmental Protection of National Development and Reform Commission,
Department of Energy and Comprehensive Utilization of Ministry of Industry
and Information Technology.
This Standard shall be under the jurisdiction of National Technical Committee
on Energy Foundation and Management of Standardization Administration of
China (SAC/TC 20).

Minimum allowable values of energy efficiency and
energy efficiency grades for electric rice cookers
1 Scope
This Standard specifies the energy efficiency grades, warm-keeping energy
consumption, standby power, minimum allowable values of energy efficiency,
energy efficiency test method and inspection rules for electric rice cookers.
This Standard is applicable to electric rice cookers working under
atmospheric environment, which take electric components or electromagnetic
induction for heating, of which the rated power is not greater than 2000 W.
