MIL-STD 461 Requirements for the Control of Electromagnetic Interference (EMI) & Characteristics of Subsystems and Equipment – U.S. Department of Defense

Created by the US Department of Defense (DoD) in 1960, the Defense Radio Frequency Compatibility Program evolved into MIL-STD-461, which was officially created in 1967. Along with MIL-STD-462 and MIL-STD-463, MIL-STD-461 was intended to be used 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 MIL-STD 463 was superseded by IEEE ANSI C63.14
