This International Standard specifies the method of using eddy current instruments for non-destructive measurements of the thickness of non-conductive coatings on non-magnetic basis me tals.
The method is applicable for measurements of the thickness of most oxide coatings produced by anodizing, but it is not applicable to all conversion coatings, some of which are too thin to be measured by this method (see clause 7).
Although, theoretically, the method can be used for measurements of the thickness of coatings on magnetic basis metals, its use for this application is not recommended. In such cases, the magnetic method specified in ISO 2178 should be used.
