3C Certification Electromagnetic Compatibility (EMC) Testing

Product Scope for 3C Mandatory Certification:

Audio and Video Equipment:

Cassette recorders/players, color/black-and-white/monochrome TV receivers (including LCD, plasma displays, and rear projection, etc.), monitors, digital TV set-top boxes, active speakers with total output power below 500W (effective value), audio power amplifiers, tuners, radios for various broadcast bands, audio and video recording/playback/processing equipment of various media formats (including cassette recorders/players, disc record players, CD/MD players, LD, VCD, Super VCD, DVD players, MP3 recorders/players, language repeaters, audio-video processing devices, etc.), audio-video systems, power adapters for audio-video equipment (including chargers).

Information Technology Equipment:

Microcomputers (PCs), servers, portable computers, display devices, internal power supplies, power adapters, chargers, printers, plotters, scanners, cash registers, computer gaming machines, and learning copiers, etc.

EMC Standards for Audio-Video and Information Technology Equipment:

Audio and Video Equipment:

- GB/T 13837-2012 "Sound and Television Broadcast Receivers and Related Equipment - Limits and Methods of Measurement of Radio Disturbance Characteristics"

- GB 17625.1-2012 "Electromagnetic Compatibility - Limits - Harmonic Current Emission Limits (Equipment Input Current ≤ 16A per Phase)"

Information Technology Equipment:

- GB/T 9254-2008 "Information Technology Equipment - Limits and Methods of Measurement of Radio Disturbance"

- GB 17625.1-2012 "Electromagnetic Compatibility - Limits - Harmonic Current Emission Limits (Equipment Input Current ≤ 16A per Phase)"

The current certification only has requirements for electromagnetic disturbance characteristics (EMI), while there are no requirements for the electromagnetic susceptibility (EMS) aspect.

EMC Testing Items in 3C Type Test:

Audio and Video Equipment:

Products must undergo all applicable EMC testing items according to the national standards GB13837 and GB17325.1.

LCD TV Testing Items:

- Disturbance voltage;

- Radiated disturbance field strength;

- Harmonic current;

- Multi-function products need comprehensive testing.

Information Technology Equipment:

EMC testing items based on national standards GB/T 9254-2008 and GB 17625:

- Disturbance voltage (0.15MHz-30MHz);

- Radiated interference field strength (30MHz-1000MHz);

- Harmonic current.

Key Components that May Affect EMC in Audio-Video and Information Technology Equipment 3C Certification:

Tuners, oscillators, switching power supplies (switching tubes, switching transformers, rectifier diodes), interference suppressors, power filters, RF modulators, power amplifiers, crystal oscillators, power cords with magnetic rings, I/O cards, HDMI cables, servo motors, transformers, and touch chips.

Latest 3C Certification Directory Scope:

Currently, the CCC certification directory is divided into 11 categories: wires and cables, circuit switches and protective or connecting devices, household and similar equipment, electronic products and safety accessories, lighting equipment, vehicles and safety accessories, security products, building materials, children's products, explosion-proof electrical, and household gas appliances.

To check whether a product requires CCC certification, refer to the CQC China Quality Certification Center's official website for comparison.
