DESCRIPTION

BS EN ISO 26423:2016


This standard BS EN ISO 26423:2016 Fine ceramics (advanced ceramics, advanced technical ceramics). Determination of coating thickness by crater-grinding method is classified in these ICS categories:
  • 81.060.30 Advanced ceramics

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.

NOTE

An alternative method for measurement of thickness, using a contact probe profilometer, is given in ISO 18452 .
