1. Introduction to CE Certification Testing for Small Household Appliances
1.1 CE Certification Testing Items for Small Household Appliances:
Certification Content: Review of product technical files; review of product circuit diagrams; determination of product certification mode.
Testing Content: There are many items that need to be tested for CE certification. The specific directives and test items involved depend on the specific product.
2. Low Voltage (LVD): Harmonic current, voltage fluctuations and flicker, current intensity, instant voltage, etc.
1.2 CE Certification EN Test Standards for Small Home Appliances:
EN60335 Safety of Household and Similar Electrical Appliances
EN55014-1 Electromagnetic Compatibility. Requirements for Household Appliances, Electric Tools and Similar Electrical Equipment. Part 1: Emission. Product Standards
EN55014-2 Electromagnetic Compatibility. Requirements for Household Appliances, Electric Tools and Similar Electrical Equipment. Part 2: Immunity. Product Standards
EN61000-3-2 Electromagnetic Compatibility (EMC). Part 3-2: Limits. Limits for Harmonic Current Emissions (Equipment Input Current 16A/phase)
EN61000-3-3 Electromagnetic Compatibility (EMC). Part 3-3: Limits. Limits for Voltage Fluctuations and Flicker in Public Low-Voltage Supply Systems (for equipment with rated current less than or equal to 16A)
The standard EMF for household appliances refers to the abbreviation EMF of Electromagnetic Fields, and the testing is based on the standard EN 62233:2008, titled "Electromagnetic field measurement and assessment methods for household and similar appliances."
2. What are the general testing standards for home appliances?
To prevent users from encountering hazards after purchasing home appliances, such hazards include electric shock, heat-related hazards, fire hazards, mechanical hazards, energy-related hazards, and radiation hazards. Home appliances need to be tested, and appliance testing includes the selection of testing standards and the testing content.
The testing standards for home appliances include safety standards and EMC (electromagnetic compatibility) standards. Safety standards include general standards and special standards. The general standard is GB4706.1 Safety of household and similar electrical appliances - General requirements, while the special standards are GB 4706.X (see attached table). The EMC testing standards include GB 4343.1-2009 Electromagnetic compatibility - Requirements for household appliances, electric tools, and similar equipment - Part 1: Emission, and GB 17625.1-2012 Electromagnetic compatibility limits - Limits for harmonic current emissions (equipment with input current per phase ≤16A).

2: Testing Content of Household Electrical Appliances
1. The testing content of household electrical appliances includes pre-inspection and testing. Pre-inspection refers to the examination conducted before testing to determine whether the product meets the standard requirements, mainly including the following three aspects:
▶ Inspection of product nameplate, used marks, and instruction manual
▶ Inspection of the product's appearance and internal structure
▶Inspection of certificates of the product's internal components
2. After the product pre-inspection, carry out safety and EMC (applicable to some home appliance products) tests. Safety testing mainly includes the following five aspects:
▶ Input power (or current) testing
▶ Heating (temperature) testing during normal operation
▶ Leakage current and high-voltage testing
▶ Abnormal condition testing
▶Heat resistance and combustion resistance testing of non-metallic materials
3. EMC testing refers to electromagnetic compatibility testing, including EMI (electromagnetic interference) testing for the magnitude of electromagnetic interference and EMS (electromagnetic susceptibility) testing for anti-interference capability. EMI testing includes the following two aspects:
▶ RE (radiated emission) testing, CE (conducted emission) testing
▶ Harmonic testing, Flicker testing
4. EMS testing includes the following four aspects:
▶ ESD (electrostatic) testing, EFT (electrical fast transient) testing
