EMI conduction test (electromagnetic interference conduction emission test) mainly assesses the electromagnetic interference signals emitted outward by electronic and electrical equipment through power lines or other wires. The following are the commonly used EMI conduction test standards in various fields:

1. International standard:

- CISPR 16: Basic Standards for EMI Testing (Measuring Equipment and Measurement Methods)

- CISPR 32/EN 55032: Limits for Conducted emissions from Information Technology Equipment (ITE)

- IEC 61000-6-3: General Standard - Emission Requirements for Residential, Commercial and Light Industrial Environments

- IEC 61000-6-4: General Standard - Emission Requirements for Industrial Environments

2. Regional standards:

North America region

FCC Part 15 Subpart B: Conducted Emission requirements for digital devices in the United States

- ANSI C63.4: American Standard for EMI Conduction Test Methods

- Medical equipment: IEC 60601-1-2

4. Test frequency range:

The frequency range of conduction tests required by most standards:

-150 KHZ -30MHz (Conductive transmission at power port)

Some standards (such as automotive electronics) may be extended to 108MHz
