MIL-STD-188/125-1, DEPARTMENT OF DEFENSE INTERFACE STANDARD: HIGH-ALTITUDE ELECTROMAGNETIC PULSE (HEMP) PROTECTION FOR GROUND-BASED C4I FACILITIES PERFORMING CRITICAL, TIME-URGENT MISSIONS (PART 1 - FIXED FACILITIES) (17 JULY 1998)

MIL-STD-188/125-1, DEPARTMENT OF DEFENSE INTERFACE STANDARD: HIGH-ALTITUDE ELECTROMAGNETIC PULSE (HEMP) PROTECTION FOR GROUND-BASED C4I FACILITIES PERFORMING CRITICAL, TIME-URGENT MISSIONS (PART 1 - FIXED FACILITIES) (17 JULY 1998)., This standard prescribes minimum performance requirements for low-risk mission-aborting damage or upset due to HEMP threat environments defined in MIL-STD-2169. This standard also addresses 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. If the prescribed testing results in any hardware damage or functional upsets, the operational authority for the facility will make the determination whether the observed event is mission aborting.
