Incercari de Compatibilitate Electromagnetica
Pentru a dezvolta activitati in domeniul incercarilor, ICMET a infiintat primul laborator modern din Romania pentru Compatibilitate Electromagnetica (CEM) destinat sa asigure compatibilitatea electromagnetica pentru echipamente electrice si electronice.
Laboratorul este rezultatul cooperarii stranse intre ICMET Craiova si Phsikalisch Technische Bundesanstalt- PTB Braunschweig, Germany.
In prezent incercarile de imunitate si masurarea perturbatiilor conduse executate de catre acest laborator sunt acreditate de catre RENAR.
In anul 2000 a fost pusa in functiune camera semi-anechoica, prima de acest fel in Romania.
