MIL-STD 461

Department of Defense, Requirements for the Control of Electromagnetic Interference Characteristics of Subsystems and Equipment

In 1960, the US Department of Defense (DoD) created a comprehensive Defense Radio Frequency Compatibility Program. In 1967 MIL-STD-461 was created. With its sister documents MIL-STD-462 and MIL-STD-463 it was intended as a tri-service EMI specification. MIL-STD 461 identified the requirements, 462 detailed them and 463 contained definitions and acronyms. MIL-STD 462 was combined with MIL-STD 461 in revision E of 1999. MIL-STD 463 was superseded by IEEE ANSI C63.14

Use and Applicability

The fundamental U.S. Military Electromagnetic Compatibility (EMC) specification. MIL-STD-461 is applied to all active U.S. Military electronics installed in DOD platforms. MIL-STD-461 is also used by many countries around the world.
