Applied Companies High Altitude Electromagnetic Pulse HEMP Design and Testing For MIL STD 188 125 2 Compliance

High-Altitude Electromagnetic Pulse (HEMP) Design and Testing For MIL-STD-188-125-2 Compliance

ECU HEMP Hardness is based on MIL-STD-188-125-2.

Classification of the ECU as Mission Critical Equipment (MCE) which must be located outside of an electromagnetic barrier

Hardening of the ECU using "Special Protective Measures" as defined in MIL-STD-188-125-2
Maximum re-use of proven HEMP-hardened ECU design
Location of Controls inside EM barrier with appropriate treatment of barrier penetrations

HEMP hardening of MCE, which must be located outside an electromagnetic barrier, is accomplished using "Special Protective Measures" (MIL-STD-188-125-2 Section 4.3.6 and Section 5.8)
Special Protective Measures (SPM) may include:
   Use of good EM-reduction layout and construction techniques
   Linear and nonlinear transient suppression / attenuation devices
   Equipment-level hardening measures
   Use of inherently robust technologies and components
   Cable, conduit and local volume shielding
Shelter EM barrier Interfaces by fiber optic connection
