Instruments for Inspection of Coatings

The long expected life of a coating system depends on surface preparation, application of the coating, quality of the material, and good inspection practices. ASTM Committees D01.43 Coatings for Power Generation Facilities and ASTM D01.46 Industrial Protective Painting are concerned with inspection. Visual standards and instruments are used to inspect various nuclear grade coatings. Magnetic and eddy current gages are used for measuring film thickness. Holiday detectors and the Elcometer adhesion tester are a part of coating inspection. /Author/
