Electromagnetic Compatibility (EMC) Testing

What is electromagnetic compatibility (EMC) testing?

Electromagnetic compatibility (EMC) testing measures the ability of equipment or systems to function satisfactorily in their electromagnetic environment without introducing intolerable electromagnetic disturbance to anything in that environment. In other words, electromagnetic compatibility testing, or EMC testing, enables you to ensure that your electrical or electronic device does not emit electromagnetic interference and it functions as expected amid various electromagnetic elements.

The two types of EMC testing include immunity testing and emissions testing. Immunity testing measures a device’s reaction when exposed to electromagnetic noise and other interruptions. On the other hand, electromagnetic interference involves measuring the amount of electromagnetic noise a device generates during normal functioning. 

TÜV SÜD offers a one-stop service for EMC testing and certification

TÜV SÜD’s experts offer comprehensive testing and certification based on their complete knowledge of EMC legislation, guidelines, and standards. Our testing can cover all types of products, from small appliances to large defence industry machines.

We assist you to resolve any EMC regulatory issues, from design concept to final production. We provide a one-stop service that covers all your testing and certification needs. Our experts provide project management to ensure that your EMC tests run smoothly.

You can choose to have tests performed at our labs, on your premises or anywhere your product is installed.

TÜV SÜD’s EMC testing procedure

Our global network of accredited labs are capable of conducting a comprehensive range of EMC tests and providing you with EMC certifications. Our EMC compliance testing covers every essential aspect, directly and indirectly, related to the electromagnetic factor of your electronic or electrical devices. Thus, the electromagnetic compatibility certification you receive is a comprehensive one issued only after thorough testing. Depending on your product, this might include:

• Antenna immunity to RF voltage
• Antenna input immunity
• Antenna screening effectiveness
• Conducted disturbances immunity
• Conducted emissions (continuous and discontinuous interference)
• Electrostatic discharge (ESD) immunity
• Electrical disturbances from conduction and coupling immunity for vehicles
• Electrical fast transient / burst immunity
• Harmonic current emission
• Harmonics and interharmonics immunity
• Immunity from radiated fields
• Immunity to induced voltages
• On-site EMC testing
• Power frequency magnetic field / oscillatory waves immunity
• Power interference
• Power supply conditioning
• Radiated emissions
• Radiated field immunity
• Voltage fluctuation / flicker
• Voltage surge immunity
• Voltage dips / interruptions immunity
• Magnetic filed measurement (EMF)
• Electric field measurement (EMF)
• Electromagnetic field measurement (EMF)
• Induced current density due to the electric field (EMF for lightning equipment)
