• Displacement speed: up to 100 mm/min
• Scoring length: max. 20 mm

Testing system:

• Sample: max. 49 x 33 mm ² , thin layers for adhesion, all materials and layers for scratch test
• Counterbody: Rockwell C diamond; Vickers diamond

Evaluation sizes:

• Adhesion of thin layers
• Crack energy density
