Measurement of coating thickness INTERNATIONAL STANDARD ISO 2360 5 Factors affecting measurement uncertainty 5.1 Coating thickness A measurement uncertainty is inherent in the method. For thin coatings, this measurement uncertainty (in absolute terms) is constant, independent of the coating thickness and, for a single measurement, is at least 0,5μm. For coatings thicker than 25 μm, the uncertainty becomes relative to the thickness and is approximately a constant fraction of that thickness. For measuring coating thicknesses of 5 μm or less,Read More …
