RS105: HEMP and NEMP Testing

Keystone Compliance has the knowledge and equipment to complete MIL-STD-461 RS105 testing. This testing is known as High Altitude Electromagnetic Pulse (HEMP) and Nuclear Electromagnetic Pulse (NEMP). The purpose of the RS105 test procedure is to verify the ability of the EUT enclosure to withstand a transient electromagnetic field. RS105 tests the susceptibility of radiated exposure a product has. MIL-STD-461 CS116 testing addresses the conducted exposure arising from a HEMP or NEMP.

MIL-STD-461 RS105 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 RS105 limit requires that 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 required waveform and amplitude. At least five pulses shall be applied at the rate of not more than one pulse per minute.
