Escopo e aplicabilidade

This standard applies to household and similar kitchen appliances with a rated voltage not exceeding AC 250V, including electric rice cookers, electric pressure cookers, electric stewing pots, electric kettles, induction cookers, and microwave ovens. It is mandatory for manufacturers of these specific kitchen appliances entering the Chinese market. It does not apply to commercial induction cookers, industrial frequency induction cookers, concave cookers, commercial microwave ovens, industrial microwave ovens, or microwave ovens with range hoods.

Requisitos técnicos

This standard specifies the energy efficiency grades (divided into 3 grades, with Grade 1 being the highest) and minimum allowable values of energy efficiency for various kitchen appliances. For most appliances, the minimum allowable value corresponds to the Grade 3 requirement. Manufacturers must ensure their products meet at least the Grade 3 limits to be compliant. The standard evaluates appliances based on heating efficiency, standby power, warm-keeping energy consumption, and for microwave ovens, off-mode power and grill-function energy consumption. It introduces specific requirements for appliances with network mode capabilities, setting distinct standby power limits for networked versus non-networked devices. The standard also details the calculation methods for heating efficiency, which vary by appliance type, taking into account factors like heating method (electric heating element vs. electromagnetic induction) and specific heat capacities of materials.

Métodos de ensaio

The standard outlines detailed testing procedures in its appendices for each appliance type. Key tests include: - Heating Efficiency Test: Measures the ratio of effective output energy to input energy under specified conditions (e.g., heating water to a certain temperature). - Standby Power Test: Measures power consumption in standby mode, with separate procedures for network mode and non-network mode. - Warm-keeping Energy Consumption Test: Measures energy used over a 5-hour period in keep-warm mode. - Off-mode Power Test (for microwave ovens): Measures power consumption when the appliance is switched off but still connected to mains power. - Grill-function Energy Consumption Test (for microwave ovens): Measures energy consumption per unit temperature rise during grill operation.

Perguntas frequentes

What products are regulated under GB 21456-2024?

GB 21456-2024 regulates household and similar kitchen appliances including electric rice cookers, electric pressure cookers, electric stewing pots and stewing cups, electric kettles, induction cookers, and microwave ovens with a rated voltage not exceeding AC 250V.

Are there any updates from the previous versions of GB 21456?

Yes, GB 21456-2024 replaces GB 12021.6-2017, GB 21456-2014, GB 24849-2017, and GB 39177-2020. Key updates include the addition of electric stewing pots and electric kettles to the scope, changes to rated power ranges, and the introduction of requirements for network mode standby power.

How does GB 21456-2024 handle appliances with network connectivity?

The standard introduces specific definitions and test methods for network mode. Appliances with network capabilities have distinct standby power limits, typically allowing a higher power consumption (e.g., ≤2.0W) compared to non-networked standby modes.

The summary above provides a high-level overview of GB 21456-2024.
