EMC (ElectroMagnetic Compatibility) Radiated and Conducted Immunity testing is used in many product industries. Different test standards are used by various industries, and the variety of test configurations and requirements can feel overwhelming to people new to the industry.
To help become familiar with some of these tests, several of the more common EMC Radiated and Conducted Immunity (also called Susceptibility) standards are listed below. These tables allow comparing some similarities and differences between various test standards. Note that these tables illustrate basic parameters, however, they do not reflect the full scope and details of the standard. Consult the applicable test standard for full details of the test requirements.
