Qeramikat speciale (qeramikat e avancuara, qeramikat teknike të avancuara) - Përcaktimi i ngjitjes së veshjeve prej qeramike me anë të provës me gërvishje (ISO 20502: 2005, duke përfshirë Cor 1: 2009)
Fine ceramics (advanced ceramics, advanced technical ceramics) - Determination of adhesion of ceramic coatings by scratch testing (ISO 20502:2005 including Cor 1:2009)
ISO 20502:2005 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 micrometres and might also be suitable for evaluating other coating types and thicknesses.
