Technical knowledge：Professional EMC Testing for Seamless Global Market Access of Your Products
Electromagnetic Compatibility (EMC) constitutes a critical consideration in electronic product design and serves as the cornerstone for enterprises' technical capabilities and global market entry. Countries worldwide have formulated relevant regulations to standardize the technical requirements for electromagnetic compatibility of products. Sharewell Certification's EMC laboratory offers comprehensive testing services, covering various testing scenarios and equipment configurations, to ensure that clients' products meet international requirements.
Conducted Emission
Conducted Emission (CE), also referred to as conducted disturbance, refers to the electromagnetic phenomenon where interference voltages or currents generated within electronic/electrical equipment or systems during operation are conducted to public networks through power lines, signal lines, or ground lines, thereby affecting the normal operation of other equipment. Almost all products connected to power sources are required to undergo conducted emission testing.

Almost all products connected to power sources are required to undergo conducted emission testing.
Purpose and Significance of Testing
- Assessing interference intensity: Measuring the degree of interference caused by disturbance voltages or currents conducted through cables from equipment during normal operation to other devices.
- Determining compliance: Comparing measurement results (disturbance voltage/current) with the limits specified in standards to judge whether the equipment meets the requirements.
- Pass: The measured value is lower than the limit.
- Fail: The measured value exceeds the limit.
- Ensuring the quality of connected networks: Ensuring that equipment connected to public networks does not cause harmful interference to other devices operating on them.
Key Points of Testing
- Main measurement frequency range: 9 kHz to 30 MHz.
- Characterization method: Disturbance voltage limit or disturbance current limit.
