Scope
ISO 26423:2009 specifies a method for the determination of the thickness of ceramic coatings by a crater grinding method, which includes the grinding of a spherical cavity and subsequent microscopic examination of the crater.
Because of the uncertainty introduced into the measurement of crater dimensions, the test is not suitable for use where the surface roughness of the coating and/or substrate exceeds 20 % of the coating thickness.
