AS 2331.1.6-1990 sets out a method for measuring the local thickness of metalliccoatings on various substrates, by micrographic examination of a taper cross-section.

This Standard sets out a method for measuring the local thickness of metallic coatings on various substrates, by micrographic examination of a taper cross-section. The method is normally applicable to coatings less than 5 mm thick. At this thickness level, an error of up to 10% can be expected.NOTE: The method is suitable for use only by personnel experienced in metallography and in the use of the appropriate equipment.
