This test method covers measurement of the local thickness of metal and oxide coatings by the microscopical examination of cross sections using an optical microscope. Coating thickness is an important factor in the performance of a coating in service and is usually specified in a coating specification. This method is suitable for acceptance testing.
WJE laboratories are accredited by ANAB (ISO/IEC 17025) to perform testing standard ASTM B487 for Measurement of Metal and Oxide Coating Thickness by Microscopical Examination of Cross Section.
