MIL-STD-462
Measurement of Electromagnetic Interference Characteristics of Subsystems
and Equipment
This page provides a summary of MIL-STD-462.
The current version of MIL-STD-462 is revision D, produced in 1993.
Mil-STD-462 establishes general testing techniques for use in the
measurement and determination of the electromagnetic emission and
susceptibility characteristics of electronic, electrical, and
electromechanical equipment and subsystems.
Test method are identified by a two letter combination followed by a
three digit number [for reference].
CE---, Conducted Emissions
RE---, Radiated Emissions
CS---, Conducted Susceptibility
RS---, Radiated Susceptibility
Testing is performed in a shielded enclosures large enough to hold the
EUT, antennas and test equipment.
Radio Frequency (RF) absorber material
shall be used when performing electric field radiated emissions or
radiated susceptibility testing to reduce reflections of electromagnetic
energy and to improve accuracy and repeatability.
The RF absorber shall
be placed above, behind, and on both sides of the EUT, and behind the
radiating or receiving antenna.
