This Technical Specification (CEN/TS) was approved by CEN on 6 June 2004 for provisional application.
The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the CEN/TS can be converted into a European Standard.
CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available
promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS)
until the final decision about the possible conversion of the CEN/TS into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France,
Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia,
Slovenia, Spain, Sweden, Switzerland and United Kingdom.

Foreword
This document (CEN/TS 1071-8:2004) has been prepared by Technical Committee CEN/TC 184 “Advanced
technical ceramics”, the secretariat of which is held by BSI.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to announce this Technical Specification: Austria, Belgium, Cyprus, Czech Republic,
Denmark, Estonia, Finland, France, Germany, Greece, Hungary Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland
and the United Kingdom.
EN 1071 Advanced technical ceramics — Methods of test for ceramic coatings consists of eleven parts:
Part 1: Determination of coating thickness by contact probe profilometer
Part 2: Determination of coating thickness by the crater grinding method
Part 3: Determination of adhesive and other mechanical failure modes by a scratch test
Part 4: Determination of chemical composition by electron probe microanalysis (EPMA)
Part 5: Determination of porosity
Part 6: Determination of the abrasion resistance of coatings by a micro-abrasion wear test
Part 7: Determination of hardness and modulus by depth sensing indentation
Part 8: Rockwell indentation test for evaluation of adhesion
Part 9: Determination of fracture strain
Part 10: Determination of coating thickness by cross sectioning
Part 11: Measurement of internal stress with the Stoney formula.
1 Scope
This document specifies a method for the evaluation of the adhesion of ceramic coatings by indentation with a
Rockwell diamond indenter. The formation of cracks after indentation may also reveal cohesive failure. The
indentations are made with a Rockwell hardness test instrument.
The method described in this document may also be suitable for evaluating the adhesion of metallic coatings.
