To prevent users from becoming dangerous after purchasing household appliances, the risks include electric shock hazard, heat hazard, fire hazard, mechanical hazard, energy hazard and radiation hazard. Household appliances need to be tested, and the testing of home appliances includes the selection of test standards and test content.
1. household appliances testing standards
The test standards for home appliances include safety test standards for home appliances and EMC test standards. Safety test standards include general and special standards. The general standard is GB4706.1 General requirements for safety of household and similar electrical appliances. The special standard is GB 4706.X (see attached table). EMC test standard is GB 4343.1-2009 "Electromagnetic compatibility of household appliances, power tools and similar appliances - Part 1: Transmission, GB 17625.1-2012 Electromagnetic compatibility limit harmonic current emission limit (device input current per phase ≤ 16A) 》.

2. Test content of household appliances
1) ：The test content of household appliances includes pre-testing and testing. Pre-testing refers to the inspection of products that meet the requirements of the standard before testing, mainly including the following three aspects:
▶ Product label, used signs, instructions check
▶ Product appearance and internal structure inspection
▶ Certificate inspection of internal parts of products
2): After the product is pre-tested, it is tested for safety and EMC (some home appliances are applicable). Safety testing mainly includes the following five aspects
▶ Input power (or current) test
▶ Normal working heat (temperature) test
▶ Leakage current and high voltage test
▶ Abnormal test
▶ Heat and flame resistance testing of non-metallic materials
3): EMC testing is electromagnetic compatibility testing, including electromagnetic field interference size EMI testing and anti-interference ability EMS testing. The EMI test includes the following two aspects:
▶ RE (radiation, emission) testing, CE (conducted interference) testing
▶ Harmonic testing, Flicker testing
4):. The EMS test includes the following four aspects:
▶ ESD（Static electricity）testing、EFT（Transient impulse interference) testing
▶ DIP(Voltage drop）testing、CS（Conducted anti-jamming）testing
▶ RS（Radiation immunity）testing、Surge(Surge lightning) testing
▶ PMS(Power frequency magnetic field immunity）testing
