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

MIL-STD-461E

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 from 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CE101: is no longer applicable to shipboard equipment.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.
