This test procedure specifies a method for measuring the local thickness of metallic coatings by examining the cross-section with a scanning electron microscope. It is destructive and has an uncertainty of less than 10% or less than 0,1 /um, whichever is greater. It can be used for thicknesses up to a few millimeters, but it is generally more practical to use a light microscope (ISO 1463). Appendix a gives the preparation of sections.
EUROLAB For numerical results, the statistical calculation will provide an assigned value with its uncertainty attached, standard deviation values for repeatability and reproducibility, warning limits for participant bias and reproducibility, individual values for the uncertainty of participants' results.
