    Abstract - (Show below) - (Hide below)

    Gives the minimum performance requirements for low-risk protection form mission-aborting damage or upset due to HEMP threat environments given in MIL-STD-2169. Also gives the minimum testing requirements for demonstrating that prescribed performance has been achieved and for verifying that the installed protection subsystem provides the operationally required hardness for the completed facility.
