Overview

This International Standard describes a method of testing ceramic coatings by scratching with a diamond stylus. During a test, either a constant or increasing force normal to the surface under test is applied to the stylus so as to promote adhesive and/or cohesive failure of the coating-substrate system. The test method is suitable for evaluating ceramic coatings up to a thickness of 20 µm and might also be suitable for evaluating other coating types and thicknesses. The International Standard is intended for use in the macro (1 to 100 N) force range. The procedures may also be applicable to other force ranges. However, appropriate calibration is essential if the normal forces at which failure occurs are to be quantified. The text of ISO 20502:2005 including Cor 1:2009 has been prepared by Technical Committee ISO/TC 206 "Fine ceramics" of the International Organization for Standardization (ISO) and has been taken over as FprEN ISO 20502:20165 by Technical Committee CEN/TC 184 "Advanced technical ceramics", the secretariat of which is held by DIN (Germany). At present a DIN committee does not exist for DIN EN 20502 since the parties concerned have not shown any interest in work on the subject.
