MIL-HDBK-237C, DEPARTMENT OF DEFENSE HANDBOOK: ELECTROMAGNETIC ENVIRONMENTAL EFFECTS AND SPECTRUM CERTIFICATION GUIDANCE FOR THE ACQUISITION PROCESS (17 JUL 2001)., This handbook provides acquisition personnel responsible for the design, development, and procurement of Department of Defense (DoD) platforms/systems and subsystems/equipment with the guidance necessary for achieving the desired level of electromagnetic (EM) compatibility (EMC). This handbook describes the tasks that should be accomplished to ensure electromagnetic environmental effects (E3) control and spectrum certification (SC) procedures are addressed during the item’s acquisition life cycle. This handbook is consistent with the policies and procedures of DoD Directives (DoDD) 5000.1, 3222.3, and 4650.1, DoD Instruction (DoDI) 5000.2, and DoD Regulation (DoDR) 5000.2-R. Provisions of this handbook should be used by research, development and acquisition activities, at appropriate times during the life cycle of any item which emits or which can be susceptible to electromagnetic energy either through intentional antennas or through other electromagnetic coupling mechanisms. Essentially, all electronics items and many electrical items fall into this classification. For example, the handbook may be used: - During acquisition to assure visibility, accountability, and controllability of the E3/SC effort, as well as its integration into the overall program, or - During the design process to assure management awareness and cost effective tailoring of applicable E3 performance requirements and interface standards. This handbook is for guidance only. This handbook cannot be cited as a requirement. If it is, the contractor does not have to comply.
