I. 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 documentation; review of product circuit diagrams; determination of product certification mode.
 

Testing content:​ There are many testing items required for CE certification. Specific products require specific judgments to determine which directives and testing items are involved.
 

Main testing items are as follows:

1. Electromagnetic Compatibility (EMC):​ Disturbance power, radiated disturbance, terminal disturbance voltage, electrostatic discharge immunity, radiated electromagnetic field immunity, conducted immunity, etc.
    
2. Low Voltage Directive (LVD):​ Harmonic current, voltage fluctuations and flicker, current intensity, transient voltage, etc.

1.2 EN Test Standards for CE Certification of Small Household Appliances

• EN 60335​ Safety of household and similar electrical appliances
   
• EN 55014-1​ Electromagnetic compatibility — Requirements for household appliances, electric tools and similar apparatus — Part 1: Emission — Product family standard
   
• EN 55014-2​ Electromagnetic compatibility — Requirements for household appliances, electric tools and similar apparatus — Part 2: Immunity — Product family standard
   
• EN 61000-3-2​ Electromagnetic compatibility (EMC) — Part 3-2: Limits — Limits for harmonic current emissions (equipment input current ≤ 16 A per phase)
   
• EN 61000-3-3​ Electromagnetic compatibility (EMC) — Part 3-3: Limits — Limitation of voltage fluctuations and flicker in public low-voltage supply systems for equipment with rated current ≤ 16 A

The standard for electromagnetic fields of household appliances is EMF​ (Electromagnetic Fields). The test is based on standard EN 62233:2008, titled "Measurement methods for electromagnetic fields of household appliances and similar apparatus with regard to human exposure."
 

II. What Are the General Test Standards for Household Appliances?

To prevent hazards to users after purchasing household appliance products, including electric shock hazards, heat-related hazards, fire hazards, mechanical hazards, energy-related hazards, and radiation hazards, household appliances must undergo testing. Testing of household appliances includes the selection of test standards and testing content.
 

Test standards for household appliances include safety test standards and EMC test standards. Safety test standards include general standards and particular standards. The general standard is GB 4706.1​ Safety of household and similar electrical appliances — General requirements. The particular standards are GB 4706.X​ (see attached table). The EMC test standards are GB 4343.1-2009​ Electromagnetic compatibility — Requirements for household appliances, electric tools and similar apparatus — Part 1: Emission, and GB 17625.1-2012​ Electromagnetic compatibility — Limits — Limits for harmonic current emissions (equipment input current ≤ 16 A per phase).

III. Testing Content for Household Appliance Products

1. The testing content for household appliances includes pre-test inspection​ and formal testing. Pre-test inspection refers to checks conducted before formal testing to determine whether the product meets standard requirements, mainly covering the following three aspects:

• ▶​ Inspection of product rating label, applied markings, and instruction manual
   
• ▶​ Inspection of product appearance and internal structure
   
• ▶​ Inspection of certificates for internal components
   

1. After pre-test inspection, safety and EMC testing (applicable to some household appliances) is conducted. Safety testing mainly includes the following five aspects:

• ▶​ Input power (or current) test
• ▶​ Temperature test under normal operation
• ▶​ Leakage current and high voltage (electric strength) test
• ▶​ Abnormal operation test
• ▶​ Heat resistance and resistance to fire test for non-metallic materials
   

1. EMC testing, i.e., electromagnetic compatibility testing, includes EMI​ (electromagnetic interference emission) testing and EMS​ (immunity/anti-interference) testing. EMI testing includes the following two aspects:

• ▶​ RE (Radiated Emission) test, CE (Conducted Emission) test
• ▶​ Harmonic test, Flicker test
   

1. EMS testing includes the following four aspects:

• ▶​ ESD (Electrostatic Discharge) test, EFT (Electrical Fast Transient) test
• ▶​ DIP (Voltage Dip and Interruption) test, CS (Conducted Susceptibility) test
• ▶​ RS (Radiated Susceptibility) test, Surge (Lightning surge) test
• ▶​ PMS (Power Frequency Magnetic Field Susceptibility) test
