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. Under good conditions, when using an optical microscope, the method is capable of giving an absolute measuring accuracy of 0. This will determine the suitability of the method for measuring the thickness of thin coatings. The method consists of cutting out a portion of the test specimen, mounting it, and preparing the mounted cross section by suitable techniques of grinding, polishing, and etching. The thickness of the cross section is then measured with 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.
