Electromagnetic Compatibility (EMC) describes the ability of electronic and electrical systems or components to function correctly when they are placed close together.

In practice- this means that electromagnetic disturbances from different equipment must be kept within limits and the equipment must possess adequate immunity to such disturbances in their environments. EMC standards are therefore developed to regulate the electromagnetic emissions from equipment, or to ensure the immunity of that equipment to electromagnetic interference (EMI).

Electromagnetic compatibility (EMC) compliance is a mandatory requirement in most markets including Europe, the U.S., China, Korea, Australia and New Zealand. EMC testing is necessary to help you meet regulatory requirements, improve product performance and reduce the risk of costly non-compliance.

Third-party electromagnetic compatibility (EMC) tests and conformity assessments also help to strengthen your competitive position in the market, and ensure that your products or projects are not delayed, re-worked, recalled or halted when non-compliance occurs.

Electromagnetic compatibility (EMC) standards have been evolving over the years. Some changes are minor while others replace old standards entirely. Keeping up with all these changes and timelines for implementation of new standards, can be tough for manufacturers.

It is important to consider electromagnetic compatibility (EMC) requirements from the beginning of the product design cycle, apply good EMC engineering practices, provide a list of sources of clock and critical electromagnetic compatibility (EMC) components, and prepare supporting equipment with satisfactory electromagnetic compatibility (EMC) performance. TÜV SÜD’s experience in electromagnetic compatibility (EMC) measurement, testing, and analysis ensures that all aspects of radio-frequency disturbances are minimized or eliminated.

TÜV SÜD’s experts offer comprehensive testing and certification based on their complete knowledge of electromagnetic compatibility (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 electromagnetic compatibility (EMC) regulatory issues, from design concept to final production.

We provide a one-stop service that covers all of your testing and certification needs. Our experts provide project management to ensure that your electromagnetic compatibility (EMC) tests run smoothly. You can choose to have tests performed at our labs, on your premises or anywhere your product is installed.
