Abstract

The scratch test is a simple engineering test method used to assess adhesive bonding between coatings and substrates. This guide aims to help you get the best out of your scratch tester. The Guide also explains the documents that you need to refer to if you want to carry out the test in a reproducible way. In particular, the Guide describes the new diamond-like carbon (DLC) coated certified material (CRM), BCR-692. Methods and strategies are described for using the CRM to compare results from different instruments and to enable the user to detect errors in the test, especially those caused by the tip of the stylus deviating from the required shape.
