The first introduction of the scratch test as a qualitative method of measuring coating adhesion was in the 1950s by Heavens [1] who applied a constant load to the sample surface via an indenter in order to damage the surface by scratching and induce delamination of the film.The applied loads that created specific damage, especially cracks or delamination, .Scratch Testing of Automotive Paint Test Results.

The test simply involves placing a fingernail on the surface and attempting a quick scratch. A properly cured and abrasive resistant coating should not scratch. The way a fingernail test is performed can be categorized as indenting, shearing and grazing actions, which vary by the way the nail interacts with the surface.
The trolley is then pulled across the test sample and the effect, if any, of the “blade” is observed. The Hoffman Tester when used in the lower range of up to 250 grams loading has been used for determining scratch resistance of a surface and is so listed in STP 500, 5.1.2.5, Paint Testing Manual, published by the ASTM.
1.1.1 Usual Procedure of the Scratch Test The scratch test consists of pressing a diamond stylus onto the surface of the coating, using either a constant or an increasing load, whilst moving the sample at a constant speed (Figure 1). The test at constant load may be a single-pass scratch test or a multiple-pass scratch test. A small or shallow scratch is deemed as one that doesn't break through the clear coat and into the paint, whereas a large or deep scratch impacts the paint, the primer, or the bare metal.
The scratch test consists of a diamond stylus moving over the surface of a sample under a normal force which is increased either stepwise or continuously until a critical normal force is reached, at which point a well-defined coating failure occurs. This force is then taken as a measure of adhesion.
