EMC Electromagnetic Compatibility Testing Introduction

Electromagnetic Compatibility (EMC) primarily focuses on the study of interference and anti-interference in electronic and electrical products. It aims to ensure that various electronic and electrical devices, equipment, or systems can operate normally without interfering with each other, achieving a state of compatibility. EMC is divided into two main categories: EMI and EMS.

 

- EMI (Electromagnetic Interference): Refers to the emission characteristics of a device, i.e., how the device emits electromagnetic disturbances to the external environment.

- EMS (Electromagnetic Susceptibility): Refers to the immunity of a device to external electromagnetic disturbances. The more sensitive a device is, the lower its immunity.

 

Scope of EMC Testing and Standards

1. IT and Information Products:

Common EMC Testing Items

1. emi testing Items

   - Harmonic current (2–40 harmonics)

   - Flicker

   - Conducted disturbance (CE)

   - Radiated disturbance (RE)

 

2. EMS Testing Items

   - Electrostatic discharge immunity (ESD)

   - Radiated electromagnetic field (80MHz–1000 MHz) immunity (RS)

   - Electrical fast transient/burst immunity

   - Surge (lightning strike) immunity

   - Conducted susceptibility (150kHz–230MHz) (CS)

   - Voltage dips and short interruptions immunity

 

Sample Requirements for EMC Testing

EMC testing requires products to be in a normal operating state. When sending samples, manufacturers should include corresponding input/output loads and accessories. Wiring instructions and installation requirements should be sent to the laboratory in advance for confirmation. If installation testing software is required, software usage instructions should also be sent to the laboratory. Usually, two sets of standard matching products are sufficient.

 

EMC Testing Timeframe

The EMC testing process typically takes around 2-3 weeks after receiving the test samples and payment. Expedited processing is available if needed. If the test fails and modifications are required, the timeframe will be extended accordingly.
