IEC 61000-2

Definition

IEC 61000-2 is an international standard that defines the electromagnetic compatibility (EMC) environment for various equipment, specifying the limits and requirements for immunity and emissions. This standard serves as a guideline for assessing how electronic devices interact with their electromagnetic environment, ensuring that natural and man-made electromagnetic interference does not adversely affect device performance. It plays a crucial role in establishing compatible operation in real-world conditions, including natural EMI sources like lightning and solar activity.
