Fine ceramics (advanced ceramics, advanced technical ceramics) - Methods of test for ceramic coatings - Determination of fracture strain (ISO 14604:2012); German version EN ISO 14604:2016

Overview
This International Standard describes a method of measuring the fracture strain of ceramic coatings by means of uniaxial tension or compression tests coupled with acoustic emission to monitor the onset of cracking of the coating. Tensile or compressive strains can also be applied by flexure using four-point bending. Measurements can be made in favourable cases at elevated temperatures as well as at room temperature. The text of ISO 14604:2012 has been prepared by Technical Committee ISO/TC 206 "Fine ceramics" of the International Organization for Standardization (ISO) and has been taken over as EN ISO 14604:2016 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 ISO 14604 since the parties concerned have not shown any interest in work on the subject.
