Coating Thickness Testing
Non-destructive thickness measurement of paint, coatings and metallic layers on steel and non-ferrous substrates by magnetic and eddy-current methods.
In short
Non-destructive thickness measurement of paint, coatings and metallic layers on steel and non-ferrous substrates by magnetic and eddy-current methods. Coating thickness testing is performed with a DeFelsko PosiTector 6000 gauge following ISO 2808 and ISO 2178/ISO 2360. Readings are verified against certified thickness standards, and multiple measurements under a defined sampling plan yield mean, minimum, maximum and standard deviation.
Coating thickness testing is performed with a DeFelsko PosiTector 6000 gauge following ISO 2808 and ISO 2178/ISO 2360. Non-magnetic coatings such as paint, powder coating and zinc on steel are measured by magnetic induction, while non-conductive coatings on non-ferrous substrates such as aluminium, copper and stainless steel are measured by eddy current. Readings are verified against certified thickness standards, and multiple measurements under a defined sampling plan yield mean, minimum, maximum and standard deviation. The service answers whether a coating meets its specified minimum thickness, how uniform the application is, how supplier batches differ and whether low thickness contributed to corrosion or adhesion failures. It serves metal finishing, automotive, structural steel, pipeline, white goods and fastener manufacturers.

How it works
Request and scoping
Substrate and coating type, expected thickness range, specification limits and the sampling plan (number and location of points) are agreed with you.
Sample reception and preparation
Specimens are logged, the surface is cleaned, measurement positions are marked and, where possible, a zero adjustment is made on the uncoated substrate.
Measurement
The gauge is verified with certified thickness shims; repeated readings are taken at each point, allowing for edge and curvature effects.
Reporting
Results are presented in the standard analysis report; supporting technical documentation is shared on request.
