This handbook provides information for use in tailoring and supplementing the electromagnetic environment (EME) levels specified in MIL-STD-464 and the radiated susceptibility requirement RS103 of MIL-STD-461. Both standards may be imposed to ensure adequate consideration of the EME in the design, development, procurement, and evaluation of Department of Defense (DoD) platforms, systems, subsystems, or equipment. This handbook is applicable to any electrical and electronic equipment, subsystem, system, or platform that may be exposed to the EME during its life cycle, including ground, ship, aircraft, aerospace and weapons systems and their associated subsystems and equipment, ordnance, and support and checkout equipments and instruments. It is intended for use by DoD personnel responsible for requirements generation and acquisition life-cycle processes, including test and evaluation of these end items. See 6.5 for tailoring guidance.
