Abstract

A method of determining direction-dependent properties of coatings, in which measurements of coating properties are made along a test track (4a, 4b) on a sample coating using one or more measuring instruments and at least one measurement is recorded in relation to direction (6). The course of the sample coating is such that there are points of identical coat thickness (2) with different coat-thickness gradients (5) along the test track.
