The electromagnetic interference caused by an Electromagnetic Pulse ( EMP ) can disrupt communications and damage electronic equipment. An EMP such as a lightning strike can physically damage objects such as buildings and aircraft. The management of EMP effects is a branch of electromagnetic compatibility (EMC) engineering.

This is a description of a procedure and test setup to verify the ability of the EUT (Equipment Under Test) enclosure to withstand a transient electromagnetic field in accordance with MIL STD 461 G – Radiated Susceptibility 105.
|This requirement is applicable to equipment and subsystem enclosures, which are exposed to the external electromagnetic environment. For surface ships, this includes external, above-deck, and exposed below-deck installations. The requirement is applicable to Army aircraft for safety critical equipment and subsystems located in an external installation. |
The EUT shall not exhibit any malfunction, degradation of performance, or deviation from specified indications, beyond the tolerances indicated in the individual equipment or subsystem specification, when subjected to a test signal having the waveform and amplitude shown in Figure RS105-1 below. At least five pulses shall be applied at the rate of not more than one pulse per minute.
