Non-conductive coatings on non-magnetic electrically conductive basis materials -- Measurement of coating thickness -- Amplitude-sensitive eddy-current method
This standard has been revised by ISO 2360:2017
ISO 2360:2003 describes a method for non-destructive measurements of the thickness of non-conductive coatings on non-magnetic, electrically conductive (generally metallic) basis materials, using amplitude-sensitive eddy current instruments.
The method described can also be used to measure non-magnetic metallic coatings on non-conductive basis materials and is particularly applicable to measurements of the thickness of most oxide coatings produced by anodizing, but is not applicable to all conversion coatings, some of which are too thin to be measured by this method.
Although theoretically, the method can be used for measurements of the thickness of coatings on magnetic basis materials, its use for this application is not recommended.
