Metallic coatings. Measurement of coating thickness. Scanning electron microscope method Ingestion-build-53008 Under positive displacement pumps are1 Scope This International Standard specifies a method for the measurement of the local thickness of metallic coatings by examination of cross sections with a scanning electron microscope (SEM). It is destructive and has an uncertainty of less than 10 % or 0,1 4m, whichever is greater. It can be used for thicknesses up to several millimetres, but it is usually more practical to use a light microscope (ISO 1463) when applicable.
