MIL-STD-461 RS105: Radiated Susceptibility, Transient Electromagnetic Field, or EMP (Electromagnetic Pulse)
The RS105 Test method is a requirement applicable to equipment and subsystem enclosures located external to a shielded platform or facility. Therefore this test is intended solely for equipment being used on non-metallic platforms. 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 an EMP waveform. At least five pulses shall be applied at the rate of not more than one pulse per minute.
There are a few variation of EMP that the RS105 requirement is testing too. Nuclear electromagnetic pulse (NEMP) is the magnetic field caused from a nuclear explosion. A high altitude nuclear EMP (HEMP) is another specific test to be performed at higher amplitudes for applications such as aircraft subsystems and components. The last military requirement is non-nuclear electromagnetic pulse (NNEMP) which includes EMP’s that are created as a weapon with the use of technology.
ATEC’s solution for testing to MIL-STD-461 RS105 is the following:
