What are the EMC testing projects? What are the common EMC testing projects? Electromagnetic compatibility (EMC) is a comprehensive evaluation of the interference level (EMI) and anti-interference ability (EMS) of electronic products in electromagnetic fields. It is one of the most important indicators of product quality. The measurement of electromagnetic compatibility consists of a testing site and testing instruments. In this article, the editor of Younai Testing breaks down which small testing projects EMC includes from these two major testing projects.

1、 EMI inspection items:

1. Conducted (CE) (150kHz~30MHz);

2. Intermittent interference voltage (clicking sound) (150kHz, 500kHz, 1.4 MHz, and 30MHz);

3. Interference power (30MHz~300MHz);

4. Harmonic current (2-40 harmonics);

5. Flashing Flicker.

2、 EMS inspection items:

1. Immunity to electrostatic discharge;

2. Radiated electromagnetic field (80MHz~1000 MHz) immunity;

3. Electrical fast transient/burst immunity;

4. Surge (lightning) immunity;

5. Injection current (150kHz~230MHz) immunity;

6. Voltage dips and short-term interruptions immunity.
