MIL-STD-461D/462D to MIL-STD-461E Changes - eEngineer


MIL-STD-461E: "DOD Interface Standard Requirements for the Control of Electromagnetic Interference Characteristics of Subsystems and Equipment" was published on August 20, 1999 and consolidates MIL-STD-461D and MIL-STD-462D into one Standard. The associated Data Item Descriptions (DIDs) are as follows:

DID NUMBER                      DID TITLE

DI-EMCS-80199B        Electromagnetic Interference Control Procedures (EMICP)
DI-EMCS-80200B        Electromagnetic Interference Test Report (EMITR)
DI-EMCS-80201B        Electromagnetic Interference Test Procedures (EMITP)

Major changes MIL-STD-461D/462D to MIL-STD-461E:

  • EUT hardware and software must be representative of production. Susceptibility scan rates and the frequency of measurement system test checks were revised.
  • Conducted Emissions

  • CE101: is no longer applicable to shipboard equipment

  • Conducted Susceptibility

  • CS101: applicability and limits were extended to 150 kHz
    CS109: measurement procedures were revised
    CS114: limits were revised
    CS115: applicability was revised for several equipment classes
    CS116: measurement procedures were revised;
              applicability was revised for several equipment classes

  • Radiated Emissions

  • RE101: the 50 cm requirement was deleted; limits are more stringent
    RE102: limits were revised for submarine equipment

  • Radiated Susceptibility

  • RS101: limits were revised for Navy applications; added an alternative test using the Helmholtz coil
    RS103: added use of mode-tuned reverberation chambers above 200 MHz
    RS105: limits were revised for consistency with IEC Standards
