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 standards)The Emitech Group carries out comprehensive test campaigns in accordance with :
