  • Traceability and wear check of tips
     


Scratch-tester Millennium

In accord with Standard EN 205 02 (formerly 1071-3), ASTM C1624, ASTM G171

Scratch test instrument for adherence characterization and scratch resistance for thin coatings and bulk materials.

The scratch-test method consists of scratching on the surface with a diamond tip on which is applied a constant or progressive load.

As the scratching is done the sample moves under the video system, to examine the different kinds of damage done by the tip and correlate it with load applied.

This standard method allows for comparison of different coatings according to substrates, thickness of coatings and preparations of surface before coating and scratch resistance of bulk materials.
