Non-conductive coatings on non-magnetic electrically conductive base metals. Measurement of coating thickness. Amplitude-sensitive eddy-current method Ingestion-build-44616 reflected in the marking of1 Scope This document specifies a method for non destructive measurements of the thickness of non conductive coatings on non magnetic electrically conductive base metals, using amplitude sensitive eddy current instruments. In this document, the term coating is used for materials such as, for example, paints and varnishes, electroplated coatings, enamel coatings, plastic coatings, claddings and powder coatings. This method is particularly applicable to
