Standard EMC militari
Nemko Spa offre test EMC secondo standard militare MIL-STD 461 D, E, F, G e RTCA/DO-160 per gli Standard dell’aviazione civile.
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:
