| ISO | 1988-10 | 8 |
Specifies a method for the measurement of the local thickness of metallic coatings by examination of cross-section with a scanning electron microscope. It is destructive and has an uncertainty of less than 10 % or 0,1 /um, whichever is greater. It can be used for thicknesses up to several millimetres, but it is usually more practical to use a ligth microscope (ISO 1463). Annex a gives the preparation of cross-sections.
