Fine ceramics (advanced ceramics, advanced technical ceramics) - Determination of coating thickness by crater-grinding method (ISO 26423:2009); German version EN ISO 26423:2016
Hochleistungskeramik - Bestimmung der Schichtdicke mit dem Kalottenschleifverfahren (ISO 26423:2009); Deutsche Fassung EN ISO 26423:2016
Overview
This International Standard 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. The text of ISO 26423:2009 has been prepared by Technical Committee ISO/TC 206 "Fine ceramics" of the International Organization for Standardization (ISO) and adopted as EN ISO 26423:2016 by CEN/TC 184 "Advanced technical ceramics", the secretariat of which is held by DIN. The committee responsible for this standard is NA 062 BR "Beirat des Normenausschusses Materialprüfung (NMP)" ("Board of DIN Standards Committee for Materials Testing (NMP)") at DIN.
