Defines a method for measuring the abrasive wear rate of ceramic coatings by means of a micro-scale abrasion wear test, based on the well known crater grinding technique used for film thickness determination.

This part of EN 1071 specifies a method for measuring the abrasive wear rate of ceramic coatings by means of a micro-scale abrasion wear test, based on the well known crater grinding technique used for film thickness determination (see EN 1071-2).

This method can provide data on both film and substrate wear rates, either by performing two separate tests or by careful analysis of data from a single test series.

The test method can be applied to samples with planar or non-planar surfaces but the analysis described in clause 9 applies only to flat samples. For non-planar samples, a more complicated analysis, possibly requiring the use of numerical methods, is required.
