Defence: qualification of military equipment
Equipment used in the defence sector must meet stringent requirements in terms of robustness, reliability and operation in extreme environments. The MIL-STD standards issued by the US Department of Defense are essential references for the qualification of such equipment and are the main technical references for EMC and environmental testing within NATO (STANAG and AECTP standards)
The Emitech Group carries out comprehensive test campaigns in accordance with :
- MIL-STD-461: electromagnetic compatibility (EMC)
- MIL-STD-704: electrical testing (aircraft power supply)
- MIL-STD-810 / 202 / 883: environmental testing (mechanical, climatic, etc.)
What areas of application are covered by the Emitech Group's services?
Our tests are aimed at players in the following sectors:
- Ground, naval and air defence
- Security, police, customs and civil protection
- Ruggedised electronics, drones, optronics, radio and radar
- On-board or fixed weapon systems
- Communication and control equipment
The Emitech Group provides comprehensive MIL-STD testing services
