- The Emitech Group now performs the RS105 test—part of the MIL-STD-461H standard—as well as its NATO equivalent, NRS03 (defined in AECTP-500), at its site in Montigny-le-Bretonneux (Yvelines, France).
- Previously outsourced, this service rounds out the group’s testing capabilities, which now cover all requirements of the MIL-STD-461H standard.
The RS105 test is designed to verify the resilience of electronic equipment against high-amplitude transient electromagnetic pulses. It is particularly relevant for equipment installed on surface vessels, aircraft, or other military platforms—especially when such equipment is directly exposed to external electromagnetic fields or integrated into structures with limited shielding.
In the laboratory, the test involves subjecting the equipment to an electromagnetic pulse that replicates the fast component of a nuclear electromagnetic pulse (NEMP). The electric field reaches a peak value of 50 kV/m, with a rise time of approximately 2 ns and a total duration of about 23 ns. The objective is to ensure that the equipment continues to function as intended, regardless of its orientation relative to the incident wave.
A modular test setup
The test system employed by Emitech combines an 80 kV high-voltage pulse generator, a 6-meter parallel-plate transmission line (stripline), and a measurement chain specifically configured to characterize nanosecond-scale pulses and high-intensity electric fields.
The installation is designed to be dismantled and transported. It takes approximately two hours to assemble and one hour to disassemble. It is currently operated within the shielded chamber at the Montigny-le-Bretonneux site, but it can also be deployed in other shielded chambers of appropriate dimensions. Emitech offers this test as a two-day service, which includes setup and dismantling.
By bringing RS105 testing in-house, the group can now handle all tests required by the MIL-STD-461H standard without needing to rely on an external laboratory. This development allows companies in the defense sector to consolidate their qualification campaigns with a single service provider in France.
