ElectroMagnetic Compatibility (EMC) testing exists to ensure that your electrical device or electronic does not emit a significant amount of electromagnetic interference and continues to work as intended amid various electromagnetic phenomena. In addition, regulatory agencies worldwide have set restrictions on the amount of pollution that electronic and electrical products emit. Additionally, electromagnetic immunity testing is required in particular places and for certain product categories. This guide will look at what you need to know about EMC.

What Is EMC And Why Is It Important?

EMC is an abbreviation for Electromagnetic Compatibility, and it refers to a circuit built to avoid interference from shielding. Electromagnetic compatibility testing is an integral part of any device’s design process. Because EMC certification is required before your product can be sold, getting this part of your design right is crucial.

Despite its importance, emissions testing is sometimes postponed until late in a product’s design life cycle. As a result, the likelihood of project delays and cost overruns nearing your intended launch increases when you don’t need the added stress.

What Are the Legalities?

To combat EMC concerns, the federal government enacted severe legislation, requiring all producers and importers of electronic devices to certify that their products are electromagnetically compatible. In addition, customers often demand that the products they purchase go through EMC testing and certification.

This ensures that the items comply with all relevant ‘CE Marking’ directives. In addition, the current legislation ensures manufacturers demonstrate EMC compliance through ElectroMagnetic Compatibility testing. It provides two primary approaches for demonstrating EMC compliance:

  • Declaration of Conformity:ElectroMagnetic Compatibility testing to synchronized standards and issuing a Declaration of Conformity.
  • Technical Construction File:Work with a ‘Competent Body’ to agree on an alternate or reduced test plan, then test and submit all required documents. This is known as the Technical Construction File.

If a case goes to court, the manufacturer can defend themselves by demonstrating that they used “all reasonable safeguards and due diligence.” I.e., the product has been verified, EMC tests have been performed, and a concerted attempt has been made not to unwittingly violate the law.

How to Reduce the Risk?

Because EMC is a subtle procedure, manufacturers struggle to determine whether their products are electromagnetically compatible. The only way to know for sure is to undertake scientific EMC tests. These must be completed with a production model and you may need to repeat it to ensure your compliance is maintained following production changes. In addition, OEM parts and accessories should be tested for compatibility with the intended use of the final product and accompanied by a Declaration of Conformity.
