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
