EMC Testing

EMC Testing is the technical process used to verify that your machinery complies with the Electromagnetic Compatibility Directive (EMC). For North American manufacturers, this is often the most challenging technical hurdle because EU requirements are stricter than US standards. Unlike the FCC, which primarily focuses on "emissions" (what your machine puts out), the EU requires you to also test for "immunity" (how your machine reacts to external noise).

Testing is typically conducted against Harmonized Standards such as EN 61000-6-4 (Industrial Emissions) and EN 61000-6-2 (Industrial Immunity). These tests subject your equipment to radiated waves, electrostatic discharge, and power surges. If your machine functions correctly under these stresses without polluting the airwaves, it passes.

For large industrial lines that cannot be moved to a lab, On-Site Testing is a valid alternative. The resulting test reports are a mandatory part of your Technical File. Without this objective evidence, you cannot sign the Declaration of Conformity (DoC), as you have no proof that the equipment will operate safely in the European electromagnetic environment.
