Résumé : |
The harmless, non-destructive NIDIT procedure can replace harmful X-ray procedures if the material under test is dielectric, i.e non-conductive. The microwave-based NIDIT procedure is described in this paper, as well as its application to the in-line inspection of extruded WPC planks. Broader application fields are obvious. |
