scope:

Purpose. This standard establishes the documentation and design requirements for the control of the electromagnetic emission and susceptibility characteristics of electronic, electrical and electromechanical equipments and subsystems (as defined herein) designed or procured for use by activities and agencies of the Department of Defense. Such equipments and subsystems may be used independently or as an integral part of other subsystems or systems.

Application. The requirements of this standard are applicable to the extent specified in the individual equipment or subsystem specification, contract or order. The applicability of the emission and susceptibility requirements are dependent upon the type of equipment or subsystem, its mission and intended installation. When engineering analyses on equipments or subsystems being procured for use in specific systems or platforms reveal that the requirements in this standard are not adequate for that procurement, they may be tailored by the procuring activity and incorporated into the request-for-proposal, specification, contract or order. In cases where a system or integrating contractor is required to prepare a detailed equipment or subsystem specification containing requirements for electromagnetic compatibility (EMC) including electromagnetic interference (EMI), electromagnetic pulse (EMP), electromagnetic (EM) radiation hazards, and so forth, the requirements of this standard shall be tailored as needed to achieve overall required system or platform performance. For equipments and subsystems in feasibility or advanced development stages of the acquisition process, this standard shall be used as a guide in formulating the appropriate requirements. Those requirements shall be enumerated in the individual equipment development or purchase description.

Units. Symbols, units and physical constants used in this standard are in accordance with the International System of Units (SI), as described in MIL-STD-463.

Emission and susceptibility designations. The emission and susceptibility requirements in this standard and corresponding test methods of MIL-STO-462 are designated in accordance with an alpha-numeric coding system where:

C = Conducted

R = Radiated

E = Emission

S = Susceptibility

UM = Unique requirement(s) intended for a miscellaneous, general-purpose equipment or subsystem
