Abstract

A method for determining the abrasion properties of a coated flat product is described. A corresponding method is proposed in which an adhesive strip is stuck to the coating of the flat product, the flat product is bent in the region provided with the adhesive strip or to be provided with the adhesive strip, the adhesive strip after bending is peeled off together with abrasion material of the coating adhering to the adhesive strip, the grey tones of the adhesive strip are determined stripe by stripe crossways to the width of the abrasion, and on the basis of the grey tones determined stripe by stripe the grey width is determined as the width of the abrasion and/or the representative grey tone is determined as the representative grey tone of the grey tones determined stripe by stripe.
