What is an EMC (electromagnetic compatibility) test designed to do?

An EMC test is primarily focused on ensuring that electrical devices do not emit excessive electromagnetic interference. This is crucial for maintaining the performance and functionality of electronic devices, as excessive interference can disrupt communications, lead to malfunctions, or degrade the performance of nearby devices.

The test examines whether an electrical device can operate as intended in its electromagnetic environment, without causing significant disruption to other devices. This is especially important in residential and commercial settings where multiple electronic devices operate in close proximity to one another. By meeting EMC standards, manufacturers help ensure that their products adhere to regulations, thereby minimizing interference and enhancing overall compatibility across devices.
