MIL-STD 461 RS105

DEPARTMENT OF DEFENSE INTERFACE STANDARD          

MIL-STD 461 RS105 Radiated Susceptibility, Transient Electromagnetic Field

This test procedure is used to verify the ability of the EUT enclosure to withstand a transient electromagnetic field.

Applicability

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.

Limit

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 on Figure RS105-1. At least five pulses shall be applied at the rate of not more than one pulse per minute.
