Indice 

1. TEST MILITARI (MIL-STD)
2. TEST AVIONICI (RTCA/DO)
3. CONTATTI

I dispositivi utilizzati in campo militare e avionico, un pò similmente a quelli medicali, vengono regolamentati con norme e direttive totalmente differenti.

Il Laboratorio EMC di Nemko Spa è in grado di eseguire alcuni test di compatibilità elettromagnetica al fine di soddisfare i requisiti richiesti dalla regolamentazioni in cui ricadono tali dispositivi:
